Partial UUID Prefix Matching in CognitiveMemoryClient

Problem

Users had to type full UUIDs when referencing memories or edges via the client. This was inconvenient — git-style short prefix matching was missing.

Solution

Added a _resolve_prefix() static method to CognitiveMemoryClient that resolves partial UUID prefixes to full IDs.

Resolution logic:

1. Check for an exact match first (pass-through if full UUID provided)
2. Scan all IDs with startswith(prefix) for partial matches
3. Single match → returns the full ID
4. Multiple matches → raises ValueError with the list of candidate IDs
5. No matches → returns None (falls through to existing behavior)

Applied to 4 functions:

• _resolve_memory_path
• _resolve_edge_path
• edge_search (both from_id and to_id params)
• related()
