fix: follow-up fixes for google-workspace gws migration

- Fix npm package name: @anthropic -> @googleworkspace/cli
- Add Homebrew install option
- Fix calendar_list to respect --start/--end args (uses raw Calendar
  API for date ranges, +agenda helper for default 7-day view)
- Improve check_auth partial scope output (list missing scopes)
- Add output format documentation with key JSON shapes
- Use npm install in troubleshooting (no Rust toolchain needed)

Follow-up to cherry-picked PR #6713

+All commands return JSON via `gws --format json`. Key output shapes:

+- **Gmail search/triage**: Array of message summaries (sender, subject, date, snippet)
+- **Gmail get/read**: Message object with headers and body text
+- **Gmail send/reply**: Confirmation with message ID
+- **Calendar list/agenda**: Array of event objects (summary, start, end, location)
+- **Calendar create**: Confirmation with event ID and htmlLink
+- **Drive search**: Array of file objects (id, name, mimeType, webViewLink)
+- **Sheets get/read**: 2D array of cell values
+- **Docs get**: Full document JSON (use `body.content` for text extraction)
