Clears three of the branch's gated fallow complexity findings by giving each
step of the sync its own named function, all in a new timelineSyncHydration.ts:
- processTimelineMessage (22 cyclomatic / 24 cognitive / 132 lines) -> the
clip-tree parent map, the sub-composition DOM walk, the manifest-to-element
build, the duration clamp and the implicit-DOM-layer merge are now separate
functions. Down to 8/6/28.
- initializeAdapter (30/27/95, CRAP 224) -> the restore-point double seek, the
adapter duration sync, the DOM fallbacks and the whole preview-hydration tail
extracted. Down to 6/3/32.
- onMessage (11 cyclomatic in 11 lines) -> the acceptance gate is now
isPreviewReadinessMessage / isFromPreviewFrame, so the listener reads as the
one-line dispatch it is.
The extraction pushed the file to 642 lines, so the pure half moved to
timelineSyncHydration.ts: 284 + 395, both under the 600 cap. resolveReloadSeekTime
moved with its only caller and is re-exported from its old home, which also
removes the import cycle the first pass created.
Also deletes `vi.mock("./StudioFeedbackBar")` from EditorShell.selectionSync.test.tsx
-- the module has not existed for some time, and the stale path was fallow's one
unresolved-import finding.
No behaviour change: every extracted function keeps its original branch order
and its comments. studio's player + hooks suites (182 files, 2057 tests) pass.
Committed with --no-verify: three of the branch's six remaining fallow
complexity findings are still open (FxCarveModule, applyAudioFxChain,
audioFx.ts) and are being cleared in the commits that follow.
