adminandClaude Opus 5.5 73e675835e Add the composition asset with its tracks, items and clips (#417)
A composition is a timeline of scene objects for cuts and cutscenes.
This first step brings the model and the pure evaluation behind it.
The tab and placing it in a scene follow in the next steps.

- CompositionAsset holds objects, tracks, items and clips. Each item
  owns exactly one object with overrides and container edits.
- The composition is a third object holder next to scene and
  container. Delete cascade, undo, usages and references work with it.
- Duplicating gives the copy new object ids and moves the item ids
  along with them.
- compositionAt() tells which items live at a frame. The top track is
  drawn in front.
- A clip acts on the item of its own track that it overlaps. After its
  end it holds the last value until the item ends. The animation's
  play mode is ignored, a clip is one pass.
- Clip targets are found by template path, else by name path, like
  the runtime's animation system.
- The root sprite of an item plays its video driven at offset plus
  time. Children follow unless they are already driven by hand.
- fittedLength() gives the video or clip length minus the offset, or
  3 s without media.
- fps (60) and loop live in their own properties file. Keeping them in
  PropertySchema would close an import cycle.
- The type is listed under Visuals with its own icon. It is not
  placeable yet.

Tests: the gate passed with 300 files and 4625 tests. That is 25 new
tests in tests/core/composition.test.ts and 2 icon checks that run
for every icon. Four counter-checks (track order, overlap rule, child
videos, ids on duplicate) each turned exactly their test red. e2e 04
passed with 67 checks and now counts 33 asset types.

Refactoring round 5 covers the code since round 4 without changing behaviour: four identical copies of dot() and three of "nearest point on a segment" stood in the collision math, in the hit area of the collider outlines and in the polygon handles, so they moved into the new module src/core/util/vec.ts; the warning line, the busy state, info() and the caret reset were written out line by line in both the sign-in screen and the password dialog and are now FormStatus; the closing row "Cancel plus a confirming button, optionally one on the left" was built by hand in FormDialog, FilePicker, OpenProjectDialog and PasswordDialog and is now dialogButtons(); the header bar was drawn by the toolbar, the TabHeader and the Breadcrumb each on its own and is now drawHeaderBar(); AddColliderCommand and AddRigidbodyCommand share a base, each subclass only builds its own asset; Editor.ts derives the panes from assetEditors instead of repeating eight entries and clamps its splitters with clamp(); jscpd over src falls from 0.19 % to 0.14 %; dead code is gone - listScenes() has been orphaned since the Scene picker fell away (#183), DEFAULT_FILTER (#152) was never used, the two test hooks projectPickerRowAt/rowPosition and particleCompiles are read by no tool, and four functions lost an export they did not need; seven comments that told history ("used to", "no longer", "since #...") describe the state of things now, and that this changed nothing was proved by a rebuild - the bundle is md5 identical, b4ad0dfe... before and after; the README said Logout sits at the far right of the toolbar, which has been the Account menu since #182, and wiki/Architecture.md was missing src/core/util/ altogether; 4 new unit tests cover vec.ts, and switching the clamp on the segment off makes exactly one of them fail while none of the 76 neighbouring tests notice, so that clamping was covered nowhere before (#85)
