feat: add quick-win features (search, templates, backup, notifications)
Tier 4 quick-win features from the product roadmap:
- Conversation search & bookmarks: full-text search across JSONL transcripts
with filters (agent, channel, since) and bookmark persistence
- Response templates: CRUD with variable expansion, per-channel overrides,
per-agent filtering
- Backup & export: create/restore with SHA256 integrity, export to
Markdown/JSON/JSONL with filtering
- Push notifications: priority-based routing, quiet hours, smart grouping,
listener API for push providers
New CLI commands:
moltbot search <query> [--agent|--channel|--since|--limit|--json|--bookmarks]
moltbot bookmark [--add|--remove|--list]
moltbot templates list|add|remove|show|update
moltbot backup create|restore|export
moltbot notifications list|read|clear|prefs (alias: notif)
51 new tests across 4 test files.
