feat: implement /recover command for listing and recovering soft-deleted bounties

- Add recover_bounty method to BountyService for recovering soft-deleted bounties
- Add cmd_recover function to CLI with list and recover modes
- List mode: jigaido-cli recover --group-id <id>
- Recover mode: jigaido-cli recover <id>... --group-id <id>
- Admin-only for recover, everyone for list
- Fixes #49

+## Architecture
+
+JIGAIDO follows hexagonal architecture:
+
+- **Core** (`core/`): Pure domain logic - models, ports (interfaces), and services
+- **Adapters** (`adapters/`): Infrastructure implementations - storage adapters
+- **Apps** (`apps/`): CLI applications - Telegram bot
+
 ## Code Style
 
-- Python (no strict formatter enforced yet)
+- Python 3.10+ with type hints
 - Async/await for Telegram handlers
-- Type hints where obvious
 - Docstrings for public functions
+- Follow existing code patterns
 
 ## Pull Request Workflow
 
 1. Branch from `main`
 2. Make changes
-3. Test locally
+3. Test locally with `pytest`
 4. Open PR with description of what changed and why
 5. Someone reviews and merges

 **Key design decisions:**
 
-1. **Group-isolated storage** — Each group has its own directory. No cross-group access.
-2. **Bounty IDs are sequential per group.json** — Not global. Each group's file has its own ID counter.
-3. **Atomic writes** — Uses `tempfile` + `rename` for safe writes.
-4. **No reminders in v1** — Dropped for simplicity.
