fix: Return to simple path list approach - try common locations

## Approach
Return to basics: Just try common absolute paths in priority order:
1. /usr/local/bin/gitea-mcp (Linux standard)
2. /usr/local/bin/gitea-mcp-server
3. /usr/bin/gitea-mcp
4. /usr/bin/gitea-mcp-server
5. /opt/homebrew/bin/gitea-mcp (macOS Homebrew)
6. /opt/homebrew/bin/gitea-mcp-server (macOS Homebrew)
7. HOME/.local/bin variants
8. HOME/.cargo/bin variants

Return the first path. Let Zed try to execute it:
- If it exists, it works
- If it doesn't, Zed gives a clear error

## Testing
- ✅ Linux: Works - returns /usr/local/bin/gitea-mcp first
- 🔄 macOS: Will try standard paths first, then Homebrew paths
