Sync my ~/.claude configuration to its Gitea repo.

## Steps

1. Change to the `~/.claude` directory
2. Run `git status` to show what has changed since the last sync
3. If there are no changes (nothing to commit, working tree clean), tell me "Config is already up to date" and stop
4. Show me a summary of the changes (new files, modified files, deleted files)
5. Stage all changes with `git add -A` (the .gitignore already excludes secrets, session data, and caches)
6. Create a commit with a descriptive message summarizing what changed (e.g., "Update skills, add new commands" or "Update Paper Dynasty workflows")
7. Push to the `origin` remote: `git push origin main`
8. Confirm success with the commit hash and a brief summary

## Important

- The remote is called `origin`
- The branch is `main`
- The .gitignore is already configured to exclude secrets, session data, memory, and caches - so `git add -A` is safe
- This command IS explicit approval to commit and push - no need to ask for confirmation
- If the push fails, show the error and suggest remediation
