spring_ease's backOut overshoot (peaks ~1.065) drove a shrinking
animation's interpolated value below its target, which could go
negative for a size request and trip GTK's height >= -1 assertion.
Previously only patched at breadbar's call sites; clamp inside
spring_to itself so the safety is automatic for every caller.
- bread-theme:🐚 WorkspacesModule.dot_widths and ClockModule.placeholder_clock,
resolved/validated in manifest.rs and modeled in types.rs, so a theme can
actually configure dot-pill widths and an entry-as-clock placeholder
instead of those staying schema-only.
- New compiled-in builtin "spotlight" (assets/shell/spotlight/), registered
in builtin.rs so list() returns three themes: centred capsule window spec
(anchors=[top] only, width=480, exclusive=none, keyboard=on_demand),
workspaces.style=dots, clock.style=none+placeholder_clock, launcher.mode=
embedded, drawer=[launcher_results]. Colours are palette token names
(pink), never hex.
- bread-theme::anim::spring_to: a reusable TickCallback size-interpolation
helper (GTK4 has no CSS width/height transition on a widget or layer-shell
surface), generalized from WorkspaceTrail's existing ease/tick pattern, for
breadbar's capsule-drawer expand/collapse.
- bread_launcher::LAUNCHER_APP: the launcher's one shared on-disk identity
(cache/config/history), so breadbar's embedded capsule and breadbox's
overlay window read and write the SAME cache and launch history rather
than forking into two rankings of a user's apps.
Tests: +6 spotlight builtin tests (loads/in list/capsule window shape/
embedded mode/dots widths/flat-pink-not-hex), bread-theme --lib 63->69,
bread-launcher --lib unchanged at 18.
