gmp e019a950b1 gtauri: Tauri v2 gallery harness WORKING on emulator
Chromium owns scroll/compositor/lazy-load/image-cache; Rust owns
scan/SQLite/thumbnail-decode behind a gallery:// custom protocol.

Hard-won gotchas (see in-code comments):
- Android: no native custom-scheme support → wry rewrites the URL to
  http://gallery.localhost/... (custom_protocol_workaround). The JS
  MUST request that form; the handler receives the reverted
  gallery://localhost/... and must strip the authority.
- tauri_build::build() in build.rs must run UNCONDITIONALLY (build
  scripts run on the host: a cfg(target_os) gate silently disables it,
  which skips the rustc-cfg=mobile emission → no mobile_entry_point →
  .so with no JNI symbols → UnsatisfiedLinkError).
- build.rs must list frontend files for rerun-if-changed (a dir-level
  directive only watches the dir mtime, not content edits) — the .so
  bakes the frontend at compile time and cargo otherwise ships stale
  UI with a 'successful' build.
- logcat drops ~75% of lines under load: use the file trace.
- fetch() is CORS-restricted (page origin http://tauri.localhost);
  <img> is not — add ACAO:* anyway.

Emulator (5853 real files): grid renders, lazy thumbs via
gallery:// with on-disk cache (87 files 35-72KB), FR log clean at
60Hz, viewer opens full-res with compositor-only pan/zoom. The single
'broken' cell is a 17-byte fake test JPEG (correct behavior).
