Context7 only re-indexes on its own popularity schedule, which is why the
existing /langbot-app/langbot-docs entry had already drifted before this
migration. Add the refresh call documented in Context7's GitHub Actions
integration so a docs change reaches the index on the same push.
The job is inert until a CONTEXT7_API_KEY secret exists, so it cannot fail
the build while the library registration is pending.
