Removes the engine's production expect() calls: background-job polling (camera, mask, roto,
point and warp tracking, render queue) uses let-else / if-let instead of take().expect("job"),
command helpers bind what they checked instead of re-reading it with expect, the menu bar falls
back to an empty tree (logged) instead of expect()ing that a constant parses, and
autotrace/text animator group lookups no longer expect a just-inserted group. perf.rs, the
benchmark harness behind `effectcraft-cli bench --ops`, opts out with a module-level allow.
Test-only unreachable!() calls become panic!() (clippy.toml allows panics in tests). Denies the
panic lints in the crate.

- footage.check: background footage check after File > Open (Progress panel), not an undo step
- timeline: track-matte / parent menus built only while open (was O(n^2) per frame);
expression-row lookup per layer; panels hold Arc<Comp> snapshots instead of deep clones
- Project panel: virtualised vertical scrolling, selection reveal, thumbnails rendered off
the UI thread
- effectcraft-cli bench --ops (engine::perf + ui-egui::bench)
