Subject: [PATCH] feat/fix: add regenerate button on failed message responses
 (#7844)

* fix: align KV cache default settings with actual runtime behavior

The documented defaults for cache_type_k and cache_type_v were f16, but
the extension's migrateKvCacheDefaults() function converts these to q8_0
on initialization. This commit updates the documented defaults to match
the actual runtime behavior.

* feat: add regenerate button on failed message responses

Show a "Regenerate" button when a message response errors out,
allowing users to retry without leaving the thread. Excludes
out-of-context-size errors which already have a dedicated button.
