Multi-select
- New `selectedLayerIds: string[]` on the scene store — ordered by
click, anchor = last entry, always equal to `selectedLayerId`.
- `toggleLayerSelection(id)` shift-click behaviour: adds or removes,
anchor follows the last click, effectively-locked layers refuse.
- `selectLayer`, `addLayer`, and every selection-reset path keep
the set in lock-step with the anchor.
Timeline
- Shift-click on a layer row's name toggles that layer's
membership in the multi-selection. Every selected row highlights
via `store.selectedLayerIds.includes(track.layerId)`.
- Right-click on a track now preserves an existing multi-selection
if the clicked track is part of it; lands as a single-select
otherwise.
- Track context menu adds two entries when ≥1 layer is selected:
- "Group N selected layers" — calls the new store action and
drops the group into the topmost selected track's stack slot
(not at the very top as a naive `addTrackGroup` would).
- "Convert N selected to clip" — packs the layers into a fresh
clip with `duration = scene.duration`, deep-clones via
`structuredClone(toRaw(l))`, drops a single `ClipInstance` on
a new clipTrack at `startTime = 0`, and positions the
clipTrack at the topmost selected track's slot.
Fixes
- `removeLayer` no longer unconditionally clears
`selectedLayerIds` (bulk-replace artifact from the multi-select
work); the anchor-matched path clears the whole set, the
non-anchor path only splices out that one id.
- `deselectIfLocked` indentation normalised.
Regression tests
- Multi-select store API: selectLayer sync, toggleLayerSelection
add/remove/anchor, lock-filter, empty-selection guards.
- `groupSelectedLayers`: happy-path packing, empty-select null
return, lock-filter, stack-slot pinning.
- `convertSelectedLayersToClip`: packs layers + spawns clipTrack +
instance (deep-clone integrity pinned via unique per-layer names
so the cloned-layer lookup is unambiguous), drops the clipTrack
at the topmost slot, returns null on empty selection, skips
effectively-locked layers.
