fix: prevent Enter from sending message during IME composition (fix #18), fix tsconfig ignoreDeprecations error (fix #17)

- Add event.isComposing check in keydown handler to prevent accidental
  message send when pressing Enter during Chinese IME input (closes #18)
- Remove invalid ignoreDeprecations: "6.0" from tsconfig.json which
  caused TS5103 error with TypeScript 5.9 (closes #17)
- Update package-lock.json after npm install
