Continues the #1815 coverage rollup. canvas-actions.ts was at 25%
in the baseline run from #2147; this PR brings the file's two
helpers to full coverage.
5 cases:
**markAllWorkspacesNeedRestart (3):**
- calls updateNodeData on every node with `{needsRestart: true}`
- no-op when the canvas has zero workspaces
- preserves call ordering — matters because the toolbar's
Restart Pending pill observes per-node data changes
incrementally; a refactor that shuffled iteration order would
silently change which workspaces flash first
**markWorkspaceNeedsRestart (2):**
- targeted call: updateNodeData fires exactly once on the named id
- defensive: regardless of how many other workspaces exist in the
store, only the target workspace gets updated. Pre-this-test, a
refactor that accidentally wired this function through the
per-node iteration path of markAll would silently mark every
workspace — pinning the cardinality here catches that.
## Mock strategy
Standard pattern for canvas store: mock useCanvasStore as both the
selector function AND a getState()-bearing object. updateNodeData
is a vi.fn() spy so the test asserts on calls + args directly.
## Test plan
- [x] All 5 cases pass locally (~132ms)
- [x] No SUT changes — pure additive coverage
- [ ] CI green
## #1815 progress
- [x] Step 1+2: instrumentation + script (#2147)
- [x] utils.ts + runtime-names.ts (#2148)
- [x] canvas-actions.ts (this PR)
- [ ] Remaining low-coverage targets: store/classNames.ts (17%),
store/canvas.ts (73% — largest absolute gap by lines)
