feat(config): move sync-branch to config.yaml as source of truth

Previously sync.branch was stored in the database via bd config set.
Now it is in config.yaml (version controlled, shared across clones):

  sync-branch: "beads-sync"

Changes:
- Add sync-branch to .beads/config.yaml
- Update syncbranch.Get() to check config.yaml before database
- Add syncbranch.GetFromYAML() and IsConfigured() for fast checks
- Update hooks to read sync-branch from config.yaml directly
- Update bd doctor to check config.yaml instead of database
- Remove auto-fix (config.yaml changes should be committed)

Precedence: BEADS_SYNC_BRANCH env > config.yaml > database (legacy)
