chore: release v0.50.1 — lint fix for React Compiler strict dep check

v0.50.0 tag was pushed but CI Build & Package job failed at the lint step:
MessageInput.tsx:184:36 "Compilation Skipped: Existing memoization could
not be preserved" — React Compiler rejected the handleSubmit useCallback
because its manually specified dep array didn't include setInputValue.
The draft-persistence change in v0.50.0 turned setInputValue into a
useCallback-wrapped function, and the dep list wasn't updated.

Fix shipped in commit 9e8c11a. No user-facing feature changes from v0.50.0.
The v0.50.0 tag is retained as a historical record (no published Release
was created by CI because lint failed before the release step).
