Summary

Add lib.rs library target for integration test support
Shared testing.rs module: test_ctx(), MockRenderer, key helpers
Fix Kitty renderer: deferred output buffer prevents stdout race with ratatui
Fix gallery detail: last_rendered cache guard prevents infinite render spam
9 integration tests covering navigation, render guard, and Kitty buffering

Prerequisite for #110, #111, #112.

Test plan

cargo test -p loom-tui — 173 tests pass (164 unit + 9 integration)
cargo clippy -p loom-tui -- -D warnings — clean
Manual: verify gallery detail image renders in Kitty without flicker

- Add lib.rs library target alongside the binary for integration test
  support. Move mod declarations from main.rs to lib.rs.
- Add testing.rs with shared test_ctx(), MockRenderer, key helpers.
  Deduplicate test_ctx() from 3 screen files.
- Add public accessors to App: process_event(), drain_actions(),
  current_screen(), screen_mut(), overlay_count().
- Fix Kitty renderer: buffer escape sequences in pending_output instead
  of writing directly to stdout. Flush after terminal.draw() completes
  to prevent interleaving with ratatui's buffered output.
- Fix gallery detail infinite render: add last_rendered cache guard to
  DetailState, skip redundant render_image() calls. Invalidate on
  zoom, pan, and selection change.
- Add flush_pending() to ImageRenderer trait (default no-op).
- Add 9 integration tests covering arrow navigation, render guard,
  mock renderer, and Kitty buffering.
