Modernize toolchain: Kotlin 2.3.10 + KSP2, sora-editor 0.24.6, drop abandoned deps (#59)

* Modernize toolchain: Kotlin 2.3.10 + KSP2, sora-editor 0.24.6, drop abandoned deps

Toolchain (Kotlin 2.1.21 -> 2.3.10, KSP 2.1.21-2.0.2 -> 2.3.9):
- KSP 2.3.x is KSP2-only; migrated Helpers.kt off the removed
  kotlinOptions/KotlinJvmOptions API to the compilerOptions DSL
  (jvmTarget = JvmTarget.JVM_17), which is a hard error under Kotlin 2.3.
- Moved the `ksp { }` room schema config to a top-level block (it is a
  project-level extension, not part of the Android DSL).
- AGP stays 8.13.2, Gradle stays 8.14.5 (verified compatible in practice).

sora-editor: editor-bom 0.23.7 -> 0.24.6 (now unblocked by Kotlin 2.3).

Remove Roomigrant (com.github.MatrixDev.Roomigrant, abandoned JitPack):
- It was already dead code: the only consumer of its generated migrations
  was a commented-out addMigrations() call. Real migration strategy is
  Room-native autoMigrations + fallbackToDestructiveMigration(), unchanged.
- Dropped both deps, the @GenerateRoomMigrations annotations/imports, and the
  now-unused jitpack repository. Room codegen verified under KSP2 (DAO/db/
  auto-migration impls still generated; schemas intact).

Replace recyclerview-fastscroll (com.simplecityapps, abandoned) with
me.zhanghai.android.fastscroll:library:1.3.0 (AndroidX-native):
- 6 layouts: FastScrollRecyclerView -> RecyclerView.
- Attach FastScrollerBuilder(...).useMd2Style().build() per list.
- App list/manager: SectionedAdapter.getSectionName -> PopupTextProvider.getPopupText.
- Dropped unused app: namespaces; removed a pre-existing no-op
  app:layout_behavior on the chain settings list (LinearLayout parent).

Verified locally on JDK 17: oss debug compile + full assembleOssRelease
(R8/minify, lintVital, desugaring) pass.

* Address Greptile review: move jvmTarget config out of android.apply; XML trailing newline

- Helpers.kt: move tasks.withType<KotlinCompile> (a project-level call) out of the
  android.apply {} block to make scope explicit, matching the top-level ksp{} block.
- layout_chain_settings.xml: restore trailing newline.
