Fix extension materialization to move bundles into container (#2339)

* Migrate extension plugin materialization layout Materialize extension plugins into a dedicated extensions/ container, validate the new manifest convention, and bump extension plugin versions. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d26008fb-9928-4ba7-b7c8-36f35320f7c1 * Keep extension manifests source-compatible Restore source extension manifests to "extensions": "." while preserving materialization-time rewrite to "extensions" in distribution output.

Also normalize misspelled-key detection strings to satisfy spelling checks without changing validation behavior.
