fix: MCP bridge built, signed, and shipped in CI releases

- Removed useless CLAUDE_MCP_SERVERS env var injection (doesn't work)
- CI builds wraith-mcp-bridge.exe as a separate cargo --bin step
- Bridge binary signed with EV cert alongside the installer
- Uploaded to Gitea packages per version
- Attached to Gitea release as a downloadable asset
- Users add to PATH then: claude mcp add wraith -- wraith-mcp-bridge
