chore(deps): upgrade wear compose libraries to 1.6.0

Align the project with the newer stable Wear Compose stack and keep local workspace artifacts out of git noise.\n\n- Bump wear compose material3/foundation/ui-tooling from 1.5.6 to 1.6.0 in version catalog\n- Add /.kotlin to .gitignore to avoid committing local Kotlin/Gradle cache metadata
