Add google-drive upload domain skill

[CrestViewFl]

Adds domain-skills/google-drive/upload.md — the working flow for uploading a local file into a Drive folder from an attached session.

Field-tested on a 75 MB mp4. Documents:

• Page.setInterceptFileChooserDialog + fileChooserOpened.backendNodeId → DOM.setFileInputFiles (Drive has no persistent file inputs; the New→File upload picker is native and undriveable otherwise)
• the guidedhelpid="new_menu_button" stable hook
• the stale-invisible-menus trap ([role=menuitem] matches closed menus — filter by visible rect)
• upload-toast polling for completion, API-side size verification
• why Drive keyboard shortcuts (Shift+U / c-then-u) don't fire via CDP on a cold folder view
• restoring the chooser interception so the user's own pickers keep working

Summary by cubic

Adds domain-skills/google-drive/upload.md, a step-by-step skill for uploading a local file into a Google Drive folder by intercepting the native file chooser via CDP. Covers stable selectors, event handling, completion polling, and pitfalls; field-tested on a 75 MB file.

• New Features
  • Reliable flow using Page.setInterceptFileChooserDialog and DOM.setFileInputFiles from fileChooserOpened.backendNodeId.
  • Stable hooks: guidedhelpid="new_menu_button"; filter visible [role=menuitem].
  • Completion via upload-toast polling; optional API verification by size.
  • Notes on restoring the chooser interception and why Drive shortcuts may not fire on a cold view.
