Eva SarafianouandCursor 1b27d5d7e2 ci: add docs CD workflow (#37421)
* ci: add docs CD workflow (P9)

Builds the Docusaurus site and deploys to S3 on every push to master
touching docs/** or api/**, then invalidates CloudFront. Splits the S3
sync into two passes so content-hashed build assets get long-lived
immutable caching while unhashed HTML stays no-cache for near-instant
propagation.

* ci: remove workflow_dispatch trigger from docs-cd

Deploys should only happen via push to master, not manual trigger.

* ci: typecheck before building docs in CD

docusaurus build strips TypeScript types via babel without validating
them, so a type error could still deploy. docs-ci.yaml typechecks the
same commit, but as an uncoupled parallel workflow it doesn't gate CD —
this catches it if CI fails or a required check is bypassed on master.

# No --delete here: old hashed assets may still be referenced by
# browser-cached HTML from a previous deploy, so let them accumulate
# (cheap) rather than risk deleting something still in use.
