* Fix cursor position bug during IME composition
Add IME composition check to BasicMessageComposer.onKeyDown to prevent
cursor position issues when pressing Tab key immediately after Japanese
input conversion. This matches the behavior in SendMessageComposer and
EditMessageComposer.
Fixes issue where cursor would jump to the beginning of the input field
after converting Japanese text and pressing Tab.
* Add tests for IME composition keydown handling
- Add test to verify keydown events are ignored during IME composition
- Add test to verify keydown events are handled normally when not composing
- Tests ensure the fix for Japanese IME cursor position bug works correctly
* Add commercial licence and update config files
* Update license in headers
* Revert "Update license in headers"
This reverts commit 7ed7949485.
* Update only spdx id
* Remove LicenseRef- from package.json
LicenseRef- no longer allowed in npm v3 package.json
This fixes the warning in the logs and failing build check.
