docs: redirect the retired tools/ and trigger URLs to integrations/

Revises the earlier fresh-start call: /tools/* are ~200 live, indexed URLs
referenced by deployed app versions' docsLink fields and marketplace listings,
so dropping them cold would 404 from the live product. next.config now 308s:
- /tools -> /integrations, /tools/:slug -> /integrations/:slug
  (custom-tools -> building-agents/custom-tools first)
- old /triggers/<service> -> /integrations/<service>, enumerated so the native
  trigger pages keep resolving; provider-slug mappings for jsm and the
  hyphenated Google/Microsoft slugs
- /blocks and /triggers index URLs -> the workflows overview anchors
Verified every class + native passthroughs against the dev server. Spec updated.
