refactor: finish the SDL3* -> Sdl3* rename and regenerate the API dumps

Picks up the file/type renames (SDL3Backend -> Sdl3Backend, SDL3FrameClock ->
Sdl3FrameClock, SDL3EventMapper.kt -> AppEvent.kt) and unifies the 15 references
the rename left behind. All were prose or strings, which is why it still
compiled:

  - a user-visible error message ("SDL3Backend received GpuMode.Auto ...")
  - two user-visible demo UI strings ("driven by the SDL3FrameClock ...")
  - the MARK headers in AppEvent.kt and Sdl3Backend.kt
  - KDoc cross-references, including to `SDL3EventMapper.kt` which no longer
    exists - repointed at AppEvent.kt
  - 3 PLAN.md references

The codebase now uses Sdl3* uniformly, matching the Sdl3MainDispatcher /
Sdl3Clipboard / Sdl3DragAndDropOwner / Sdl3ScrollConfig that already followed
that form. `sdl3.*` (the cinterop package) and SDL_* (the C API) are untouched.

API dumps regenerated: a clean 1:1 rename, 41 SDL3Backend -> 41 Sdl3Backend in
:ui and nothing else - the other renamed types were not public. Breaking, but
com.compose.sdl only; no androidx.compose.* / org.jetbrains.compose.* change.

Verified beyond compiling: apiCheck green, both metadata publish gates compile,
nav3test/backtest/multiwintest PASS, raw SDL handles still resolve
(gpu=OpenGL window=true glContext=true), and the Images screen renders.
