Adds the Kotlin Compose Compiler plugin to :AnkiDroid, pulls in Compose BOM 2026.04.01 with material3, ui-tooling, activity-compose and the lifecycle-compose pair, and opts in to ExperimentalMaterial3Api at the module level so screens don't need @OptIn annotations. The Compose Compiler attaches to every Kotlin compilation in the module, so testFixtures (which has no @composable code) needs the runtime on its compileOnly classpath to satisfy the plugin's version check. Also relaxes ktlint's function-naming rule for @composable functions so PascalCase composables don't trip the linter.

Purpose / Description
Enable Jetpack Compose on the :AnkiDroid module so future screens can be built or migrated incrementally. This follows Google's I/O 2026 "Compose-First" direction. This PR is foundational it does not convert any existing user-facing screen.
Fixes
Approach
See commit 1 and then:
Added
com.ichi2.compose.theme.Themethat reads colors from the host Activity's XML theme via R.styleable.ComposeTheme and bridges each of the four AnkiDroid themes (Light, Plain, Dark, Black) into a Material 3 ColorScheme. Slots not declared by the XML fall back to Material 3 defaults; isLightTheme (inherited from Theme.Material3.{Light,Dark}) decides the base scheme.How Has This Been Tested?
Local build passed
Learning (optional, can help others)
Themes and Preview is a mess to handle for custom themes and it took me whole night to enable compose for Shared Deck screen
