Add Google Drive context source

[luca-martial]

Scope

Build a gdrive context-source adapter that ingests Google Docs from a configured Drive folder and converts them to Markdown.

Where to start

• Adapter directory: packages/context/src/ingest/adapters/gdrive/
• Model on packages/context/src/ingest/adapters/notion/
• Use Google Drive API (list files) + Google Docs API (read content)
• Auth via service account JSON key
• Wire the new driver value in packages/context/src/project/driver-schemas.ts
• Add docs in docs-site/content/docs/integrations/context-sources.mdx

Acceptance criteria

• New adapter under adapters/gdrive/ with tests
• Lists Google Docs under a configured folder ID (recursive optional)
• Converts Docs to Markdown, preserving headings and lists
• Authentication uses service-account key via file:/path/to/key.json
• Integration docs added with the required Drive API scopes
