Merge branch 'main' into dev

Resolve 38 conflicts preserving both sides' work:
- Server: DB-based registries (dev) + WorkspaceGitService/DaemonConfigStore (main)
- App: script proxy/voice MCP (dev) + pin/hide tabs/bootstrap boundary (main)
- Shared: WorkspaceScriptPayload (dev) + git/GitHub runtime schemas (main)
- Deleted workspace-registry-bootstrap.ts (dev's DB approach supersedes)
