feat(config): support daemon.auto_* settings in config.yaml (GH#871)

Allow team-wide auto-sync configuration via config.yaml instead of SQLite.
This enables teams to share auto-commit/auto-push settings through version control.

Changes:
- Add daemon.auto_commit, daemon.auto_push, daemon.auto_pull to YamlOnlyKeys
- Add daemon.* prefix to YAML-only prefixes
- Update daemon startup to read from config.yaml first, then fall back to SQLite
- Update bd init --team to write daemon settings to config.yaml

Usage:
  # In .beads/config.yaml (version controlled, shared by team)
  daemon.auto_commit: true
  daemon.auto_push: true

  # Or via bd config set
  bd config set daemon.auto_commit true
