CLAUDE: Add logged_command decorator and migrate Discord commands to reduce boilerplate

- Add @logged_command decorator in utils/decorators.py to eliminate try/catch/finally boilerplate
- Migrate all Discord commands to use new decorator pattern:
  * commands/league/info.py - /league command
  * commands/players/info.py - /player command
  * commands/teams/info.py - /team and /teams commands
  * commands/teams/roster.py - /roster command
- Fix PyLance type issues by making model IDs required for database entities
- Update Player and Team models to require id field since they come from database
- Fix test cases to provide required id values
- Add comprehensive test coverage for decorator functionality
- Add migration guide for applying decorator to additional commands
- Reduce codebase by ~100 lines of repetitive logging boilerplate

+# Discord Bot v2.0 - Logging Decorator Migration Guide
+
+This guide documents the process for migrating existing Discord commands to use the new `@logged_command` decorator, which eliminates boilerplate logging code and standardizes command logging patterns.
+
+## Overview
+
+The `@logged_command` decorator automatically handles:
+- Discord context setting with interaction details
+- Operation timing and trace ID generation
+- Command start/completion/failure logging
+- Exception handling and logging
+- Parameter logging with exclusion options
+
+## What Was Changed
+
+### Before (Manual Logging Pattern)
+```python
+@discord.app_commands.command(name="roster", description="Display team roster")
+async def team_roster(self, interaction: discord.Interaction, abbrev: str):
+    set_discord_context(interaction=interaction, command="/roster")
+    trace_id = logger.start_operation("team_roster_command")
+    
+    try:
+        logger.info("Team roster command started")
+        # Business logic here
+        logger.info("Team roster command completed successfully")
+        
+    except Exception as e:
+        logger.error("Team roster command failed", error=e)
+        # Error handling
+        
+    finally:
+        logger.end_operation(trace_id)
+```
+
+### After (With Decorator)
+```python
+@discord.app_commands.command(name="roster", description="Display team roster")
+@logged_command("/roster")
+async def team_roster(self, interaction: discord.Interaction, abbrev: str):
+    # Business logic only - no logging boilerplate needed
+    # All try/catch/finally logging is handled automatically
+```
+
+## Step-by-Step Migration Process
+
+### 1. Update Imports
+
+**Add the decorator import:**
+```python
+from utils.decorators import logged_command
+```
+
+**Remove unused logging imports (if no longer needed):**
+```python
+# Remove if not used elsewhere in the file:
+from utils.logging import set_discord_context  # Usually can be removed
+```
+
+### 2. Ensure Class Has Logger
+
+**Before migration, ensure the command class has a logger:**
+```python
+class YourCommandCog(commands.Cog):
+    def __init__(self, bot: commands.Bot):
+        self.bot = bot
+        self.logger = get_contextual_logger(f'{__name__}.YourCommandCog')  # Add this line
+```
+
+### 3. Apply the Decorator
+
+**Add the decorator above the command method:**
+```python
+@discord.app_commands.command(name="your-command", description="...")
+@logged_command("/your-command")  # Add this line
+async def your_command_method(self, interaction, ...):
+```
+
+### 4. Remove Manual Logging Boilerplate
+
+**Remove these patterns:**
+- `set_discord_context(interaction=interaction, command="...")`
+- `trace_id = logger.start_operation("...")`
+- `try:` / `except:` / `finally:` blocks used only for logging
+- `logger.info("Command started")` and `logger.info("Command completed")`
+- `logger.error("Command failed", error=e)` in catch blocks
+- `logger.end_operation(trace_id)`
+
+**Keep these:**
+- Business logic logging (e.g., `logger.info("Team found", team_id=123)`)
+- Specific error handling (user-facing error messages)
+- All business logic and Discord interaction code
+
+### 5. Test the Migration
+
+**Run the tests to ensure the migration works:**
+```bash
+python -m pytest tests/test_utils_decorators.py -v
+python -m pytest  # Run all tests to ensure no regressions
+```
+
+## Example: Complete Migration
+
+### commands/teams/roster.py (BEFORE)
+```python

+        trace_id = logger.start_operation("team_roster_command")
+        
+        try:
+            await interaction.response.defer()

+
+## Migration Checklist for Each Command
+
+- [ ] Add `from utils.decorators import logged_command` import
+- [ ] Ensure class has `self.logger = get_contextual_logger(...)` in `__init__`
+- [ ] Add `@logged_command("/command-name")` decorator
+- [ ] Remove `set_discord_context()` call
+- [ ] Remove `trace_id = logger.start_operation()` call
+- [ ] Remove `try:` block (if only used for logging)
+- [ ] Remove `logger.info("Command started")` and `logger.info("Command completed")`
+- [ ] Remove generic `except Exception as e:` blocks (if only used for logging)
+- [ ] Remove `logger.error("Command failed")` calls
+- [ ] Remove `finally:` block and `logger.end_operation()` call
+- [ ] Keep business logic logging (specific info/debug/warning messages)
+- [ ] Keep error handling that sends user-facing messages
+- [ ] Test the command works correctly
+
+## Decorator Options
+
+### Basic Usage
+```python
+@logged_command("/command-name")
+async def my_command(self, interaction, param1: str):
+    # Implementation
+```
+
+### Auto-Detect Command Name
+```python
+@logged_command()  # Will use "/my-command" based on function name
+async def my_command(self, interaction, param1: str):
+    # Implementation
+```
+
+### Exclude Sensitive Parameters
+```python
+@logged_command("/login", exclude_params=["password", "token"])
+async def login_command(self, interaction, username: str, password: str):
+    # password won't appear in logs
+```
+
+### Disable Parameter Logging
+```python
+@logged_command("/sensitive-command", log_params=False)
+async def sensitive_command(self, interaction, sensitive_data: str):
+    # No parameters will be logged
+```
+
+## Expected Benefits
+
+### Lines of Code Reduction
+- **Before**: ~25-35 lines per command (including try/catch/finally)
+- **After**: ~10-15 lines per command
+- **Reduction**: ~15-20 lines of boilerplate per command
+
+### Consistency Improvements
+- Standardized logging format across all commands
+- Consistent error handling patterns
+- Automatic trace ID generation and correlation
+- Reduced chance of logging bugs (forgotten `end_operation`, etc.)
+
+### Maintainability
+- Single point of change for logging behavior
+- Easier to add new logging features (e.g., performance metrics)
+- Less code duplication
+- Clearer separation of business logic and infrastructure
+
+## Files to Migrate
+
+Based on the current codebase structure, these files likely need migration:
+
+```
+commands/
+├── league/
+│   └── info.py
+├── players/
+│   └── info.py
+└── teams/
+    ├── info.py
+    └── roster.py  # ✅ Already migrated (example)
+```
+
+## Testing Migration
+
+### 1. Unit Tests
+```bash
+# Test the decorator itself
+python -m pytest tests/test_utils_decorators.py -v
+
+# Test migrated commands still work
+python -m pytest tests/ -v
+```
+
+### 2. Integration Testing
+```bash
+# Verify command registration still works
+python -c "
+import discord
+from commands.teams.roster import TeamRosterCommands
+from discord.ext import commands
+
+intents = discord.Intents.default()
+bot = commands.Bot(command_prefix='!', intents=intents)
+cog = TeamRosterCommands(bot)
+print('✅ Command loads successfully')
+"
+```
+
+### 3. Log Output Verification
+After migration, verify that log entries still contain:
+- Correct trace IDs for request correlation
+- Command start/completion messages
+- Error logging with exceptions
+- Business logic messages
+- Discord context (user_id, guild_id, etc.)
+
+## Troubleshooting
+
+### Common Issues
+
+**Issue**: `AttributeError: 'YourCog' object has no attribute 'logger'`
+**Solution**: Add `self.logger = get_contextual_logger(...)` to the cog's `__init__` method
+
+**Issue**: Parameters not appearing in logs
+**Solution**: Check if parameters are in the `exclude_params` list or if `log_params=False`
+
+**Issue**: Command not registering with Discord
+**Solution**: Ensure `@logged_command()` is placed AFTER `@discord.app_commands.command()`
+
+**Issue**: Signature errors during command registration
+**Solution**: The decorator preserves signatures automatically; if issues persist, check Discord.py version compatibility
+
+### Debugging Steps
+
+1. Check that all imports are correct
+2. Verify logger exists on the cog instance
+3. Run unit tests to ensure decorator functionality
+4. Check log files for expected trace IDs and messages
+5. Test command execution in a development environment
+
+## Migration Timeline
+
+**Recommended approach**: Migrate one command at a time and test thoroughly before moving to the next.
+
+1. **Phase 1**: Migrate simple commands (no complex error handling)
+2. **Phase 2**: Migrate commands with custom error handling
+3. **Phase 3**: Migrate complex commands with multiple operations
+4. **Phase 4**: Update documentation and add any additional decorator features
+
+This approach ensures that any issues can be isolated and resolved before affecting multiple commands.

+    Decorator for Discord commands that adds comprehensive logging.
+    
+    This decorator automatically handles:
+    - Setting Discord context with interaction details
+    - Starting/ending operation timing
+    - Logging command start/completion/failure
+    - Preserving function metadata and signature
+    
+    Args:
+        command_name: Override command name (defaults to function name with slashes)
+        log_params: Whether to log command parameters (default: True)
+        exclude_params: List of parameter names to exclude from logging
+        
+    Example:
+        @logged_command("/roster", exclude_params=["sensitive_data"])
+        async def team_roster(self, interaction, team_name: str, season: int = None):
+            # Clean business logic only - no logging boilerplate needed

+            embed = create_roster_embed(team, players)
+            await interaction.followup.send(embed=embed)
+    
+    Side Effects:
+        - Automatically sets Discord context for all subsequent log entries
+        - Creates trace_id for request correlation
+        - Logs command execution timing and results
+        - Re-raises all exceptions after logging (preserves original behavior)
+    
+    Requirements:
+        - The decorated class must have a 'logger' attribute, or one will be created
+        - Function must be an async method with (self, interaction, ...) signature
+        - Preserves Discord.py command registration compatibility
