gsxdsm f58fb8955a fix(engine-tests): eliminate temp-dir leak and raise subprocess guard for concurrent workspace runs
Two engine merger tests created mkdtempSync workspaces directly in tmpdir()
under the tracked `fusion-test-` prefix; under full-suite concurrent load
the post-run check-test-isolation flagged them as leaks. Route both
(`merger-no-op-fix-finalize.test.ts`, `merger-verification-fix-already-on-main.test.ts`)
through FUSION_TEST_WORKER_ROOT like sibling merger tests so they nest
inside the already-tracked worker root.

Bump engine vitest subprocess guard from 60s to 120s and testTimeout to
30s — plain git commands (branch -d, worktree remove) queued behind
system contention during `pnpm -r --workspace-concurrency=2` runs were
timing out. The guard only fires on hangs, so healthy tests pay nothing.

Also bundles in-progress dashboard mobile-breakpoint regex/CSS test
updates and docs index additions.

fix(engine-tests): eliminate full-suite temp-dir leak and harden subprocess guard against concurrent-workspace contention.

  • Two engine merger tests (merger-no-op-fix-finalize.test.ts, merger-verification-fix-already-on-main.test.ts) created mkdtempSync workspaces directly under tmpdir() with the tracked fusion-test- prefix. Under pnpm -r --workspace-concurrency=2 load, transient cleanup races left orphans flagged by check-test-isolation. Route both through FUSION_TEST_WORKER_ROOT like sibling merger tests so the dirs nest inside the already-tracked worker root and never appear as top-level leaks.

  • Bump the engine vitest subprocess guard from 60 s to 120 s and the per-test timeout to 30 s. Under concurrent workspace runs, plain git commands (git branch -d, git worktree remove --force) queued behind system contention were timing out and failing reliability-interactions tests. The guard fires only on hangs, so healthy tests pay nothing for the higher ceiling.
