feat(drive): add activity query for audit trails (Activity API v2)

[dl-alexandre]

Summary

Add Google Drive Activity API v2 support for audit trails, compliance monitoring, and security investigations.

Current State

gog drive has no activity tracking. This is the Drive Activity API (distinct from Gmail History API / gmail watch serve).

Proposed Commands

gog drive activity query                          # Recent activity across Drive
gog drive activity query --file <fileId>          # Activity for specific file
gog drive activity query --folder <folderId>      # Activity for folder tree
gog drive activity query --user user@example.com  # Activity by user
gog drive activity query --actions edit,share --from 2026-01-01T00:00:00Z

Use Cases

• Compliance auditing: who accessed what and when
• Security monitoring: detect unauthorized access patterns
• Incident investigation: trace file lifecycle events
• Access tracking: monitor sensitive document interactions

API Notes

• API: https://developers.google.com/drive/activity/v2
• Additional scope: https://www.googleapis.com/auth/drive.activity.readonly
• Supports filtering by action types (edit, comment, share, permission_change, etc.)

None — this is a new capability distinct from Gmail history.

I've implemented this in another Drive CLI and can share implementation details if helpful.
