feat(google-appsheet): add Google AppSheet integration (#5376)

* feat(google-appsheet): add Google AppSheet integration

- 4 tools (find/add/edit/delete rows) against the AppSheet Action API
- API key auth via Application Access Key (no OAuth/scopes needed)
- Block with operation dropdown, region selector, and Selector expression support
- Generated docs

* improvement(google-appsheet): harden response parsing, add wand config and skills

- Guard against empty/non-JSON AppSheet response bodies (Delete may return no body)
- Add wandConfig to the Selector field for AI-assisted expression generation
- Add 3 skills grounded in attested AppSheet/Zapier automation patterns
- Tighten json output descriptions to describe inner shape

* fix(google-appsheet): validate region against allow-list, encode appId, validate rows shape

- Reject unrecognized region values instead of interpolating them into the
  request host (a caller could otherwise redirect the Application Access
  Key to an arbitrary domain)
- URL-encode appId, not just tableName, in the Action endpoint path
- Reject non-array Rows input in tools.config.params instead of forwarding
  a single object to the AppSheet Action API
- Drop the mismatched json-object generationType on the rows wand config
  (that enricher appends "must start with { and end with }", which
  conflicts with the JSON-array shape the field expects)
- Add utils.test.ts covering region validation and response-body parsing

* docs(google-appsheet): add manual intro/getting-started section

Match the MANUAL-CONTENT convention used by other integration docs
(Airtable, Ahrefs, Google PageSpeed) — an overview of the service, what
the Sim integration lets agents do, and how to get an Application
Access Key.

* docs: sync generated integration docs with current source

Regenerate docs for integrations whose tools/blocks changed upstream
without a matching docs regen (ahrefs, algolia, amplitude, brex, clerk,
gong, hex, langsmith, loops, onepassword, sendgrid, sharepoint,
similarweb, supabase, tailscale, trello, vercel, wordpress), plus the
integrations.json catalog.
