feat: Add Gitea MCP integration and project cleanup

## New Features
- **Gitea MCP Tools** (zero API cost):
  - gitea_read_file: Read files from homelab repo
  - gitea_list_files: Browse directories
  - gitea_search_code: Search by filename
  - gitea_get_tree: Get directory tree
- **Gitea Client** (gitea_tools/client.py): REST API wrapper with OAuth
- **Proxmox SSH Scripts** (scripts/): Homelab data collection utilities
- **Obsidian MCP Support** (obsidian_mcp.py): Advanced vault operations
- **Voice Integration Plan** (JARVIS_VOICE_INTEGRATION_PLAN.md)

## Improvements
- **Increased timeout**: 5min → 10min for complex tasks (llm_interface.py)
- **Removed Direct API fallback**: Gitea tools are MCP-only (zero cost)
- **Updated .env.example**: Added Obsidian MCP configuration
- **Enhanced .gitignore**: Protect personal memory files (SOUL.md, MEMORY.md)

## Cleanup
- Deleted 24 obsolete files (temp/test/experimental scripts, outdated docs)
- Untracked personal memory files (SOUL.md, MEMORY.md now in .gitignore)
- Removed: AGENT_SDK_IMPLEMENTATION.md, HYBRID_SEARCH_SUMMARY.md,
  IMPLEMENTATION_SUMMARY.md, MIGRATION.md, test_agent_sdk.py, etc.

## Configuration
- Added config/gitea_config.example.yaml (Gitea setup template)
- Added config/obsidian_mcp.example.yaml (Obsidian MCP template)
- Updated scheduled_tasks.yaml with new task examples
