Library tab gets a cycling filter (all/series/movies/missing/unmonitored)
and sort (title/missing/kind), color-coded kind tags and missing-count
severity, and monitor-toggle without opening detail. Keybinding hints move
out of cramped block titles into a context-aware status bar plus a `?`
help overlay, both driven by one shared keybinding table so they can't
drift apart. Episode status icons and review-queue confidence get the same
severity coloring. Stuck tab gains real selection/focus and can jump
straight to a show's Library detail (needed adding media_item_id to
StalledGrab's query — the one small backend touch in this pass). Adds a
manual refresh-now key.
expand_home() fell through to PathBuf::from(input) — the literal,
unexpanded "~/..." string — whenever the HOME env var itself wasn't set,
same bug class as breadclip-core/breadpad-shared/breadmon (found during
this pass's own crate-migration sweep, in a different shape here: the bug
was in this crate's own tilde-expansion helper rather than a
dirs::xxx().unwrap_or_else() chain). Fixed via bread_utils::xdg::home_dir,
which resolves a real home directory before ever needing to fall back.
Builds and tests clean: 205 passed, 1 pre-existing network-dependent test
ignored, 0 failed.
