## [2.2.0] - 2025-12-21

### 🚀 Private Config Repositories - Team Collaboration Unlocked

This major release adds **git-based config sources**, enabling teams to fetch configs from private/team repositories in addition to the public API. This unlocks team collaboration, enterprise deployment, and custom config collections.

### 🎯 Major Features

#### Git-Based Config Sources (Issue [#211](https://github.com/yusufkaraaslan/Skill_Seekers/issues/211))
- **Multi-source config management** - Fetch from API, git URL, or named sources
- **Private repository support** - GitHub, GitLab, Bitbucket, Gitea, and custom git servers
- **Team collaboration** - Share configs across 3-5 person teams with version control
- **Enterprise scale** - Support 500+ developers with priority-based resolution
- **Secure authentication** - Environment variable tokens only (GITHUB_TOKEN, GITLAB_TOKEN, etc.)
- **Intelligent caching** - Shallow clone (10-50x faster), auto-pull updates
- **Offline mode** - Works with cached repos when offline
- **Backward compatible** - Existing API-based configs work unchanged

#### New MCP Tools
- **`add_config_source`** - Register git repositories as config sources
  - Auto-detects source type (GitHub, GitLab, etc.)
  - Auto-selects token environment variable
  - Priority-based resolution for multiple sources
  - SSH URL support (auto-converts to HTTPS + token)

- **`list_config_sources`** - View all registered sources
  - Shows git URL, branch, priority, token env
  - Filter by enabled/disabled status
  - Sorted by priority (lower = higher priority)

- **`remove_config_source`** - Unregister sources
  - Removes from registry (cache preserved for offline use)
  - Helpful error messages with available sources

- **Enhanced `fetch_config`** - Three modes
  1. **Named source mode** - `fetch_config(source="team", config_name="react-custom")`
  2. **Git URL mode** - `fetch_config(git_url="https://...", config_name="react-custom")`
  3. **API mode** - `fetch_config(config_name="react")` (unchanged)

  - `clone_or_pull()` - Shallow clone with auto-pull and force refresh
  - `find_configs()` - Recursive *.json discovery (excludes .git)
  - `get_config()` - Load config with case-insensitive matching
  - `inject_token()` - Convert SSH to HTTPS with token authentication
  - `validate_git_url()` - Support HTTPS, SSH, and file:// URLs

add_config_source(name="team", git_url="https://github.com/myteam/configs.git")

# Daily usage
fetch_config(source="team", config_name="react-internal")
```

**Enterprise (500+ developers):**
```bash
# IT pre-configures sources
add_config_source(name="platform", ..., priority=1)
add_config_source(name="mobile", ..., priority=2)

# Developers use transparently
fetch_config(config_name="platform-api")  # Finds in platform source
```

**Example Repository:**
```bash
cd /path/to/Skill_Seekers
python3 configs/example-team/test_e2e.py  # Test E2E workflow
```

### Backward Compatibility
- ✅ All existing configs work unchanged
- ✅ API mode still default (no registration needed)
- ✅ No breaking changes to MCP tools or CLI
- ✅ New parameters are optional (git_url, source, refresh)

### Security
- ✅ Tokens via environment variables only (not in files)
- ✅ Shallow clones minimize attack surface
- ✅ No token storage in registry file
- ✅ Secure token injection (auto-converts SSH to HTTPS)

### Performance
- ✅ Shallow clone: 10-50x faster than full clone
- ✅ Minimal disk space (no git history)
- ✅ Auto-pull: Only fetches changes (not full re-clone)
- ✅ Offline mode: Works with cached repos

### Files Changed
- Modified (2): `pyproject.toml`, `src/skill_seekers/mcp/server.py`
- Added (6): 3 source files + 3 test files + 1 doc + 1 example repo
- Total lines added: ~2,600

### Migration Guide

No migration needed! This is purely additive:

```python
# Before v2.2.0 (still works)
fetch_config(config_name="react")

# New in v2.2.0 (optional)
add_config_source(name="team", git_url="...")
fetch_config(source="team", config_name="react-custom")
```

### Known Limitations
- MCP async tests require pytest-asyncio (added to dev dependencies)
- Example repository uses 'master' branch (git init default)
