Starling Agent v0.0.8

What's changed

• Catalog expand now uses batched session lookup. Expanding a catalog with
  many pins (e.g. cc-mi-2.5 with 360 pins) previously spawned one
  starling session show subprocess per pin. Now a single
  starling session lookup <ids...> --json resolves all of them in one pass.
  Requires Starling CLI >= v0.0.11 for the session lookup subcommand; falls
  back automatically to per-id lookups on older CLIs.
• hydratePinSessions in spaces.ts collapses N subprocess spawns into 1.
• First paint renders PinNodes from bookmark data; model / modified / token
  fields fill in from the single batch call.

Verification

• npm run compile
• npx @vscode/vsce package
• Manual smoke against CLI v0.0.11
