Code Review
This pull request adds deprecation notices and replacement comments to the PREINSTALL.md and README.md files of several Firebase extensions, directing users to migrate to their corresponding scoped npm packages. There are no review comments, so I have no feedback to provide.

Adds a machine-readable deprecation marker plus a visible deprecation notice to each extension whose replacement kit exists on the

PREINSTALL.mdand the READMEs are regenerated withlerna run generate-readme(firebase ext:info --markdown), since READMEs are generated files.Marker format (HTML comment, invisible when rendered):

Notes
firestore-shorten-urls-bitlyhas no kit yet, so no marker.googlecloud/*extensions (firestore-genai-chatbot, firestore-incremental-capture, speech-to-text, firestore-vector-search, bigquery-firestore-export) andfirestore-bundle-builderneed the same treatment in their own source repos - separate PRs.
