Strengthens regression test coverage for worker-budget behavior in the vitest workers test suite, adding 14 lines to cover edge cases.

- pnpm build now excludes @fusion/desktop and @fusion/mobile by default
(recursive build still available as pnpm build:all). Saves time on
workspace-wide builds that don't need the native shells.
- Hoist the per-package max-worker computation into a shared
packages/core/src/__test-utils__/vitest-workers.ts util. Every
vitest.config.ts now calls computeMaxWorkers(), which honors
VITEST_MAX_WORKERS, FUSION_TEST_TOTAL_WORKERS, and a per-config
defaultCap, clamped to cpus-1.
- pnpm test sets VITEST_MAX_WORKERS=2 so the workspace run keeps total
fan-out modest with --workspace-concurrency=2.
- Switch dashboard vitest pool from forks to threads so jsdom/React
suites share a V8 heap instead of duplicating ~500MB per worker.

The vitest child-process guard wrapped exec/execFile without preserving the
`[util.promisify.custom]` symbol, so awaited `execAsync` resolved to a raw
stdout string instead of `{stdout, stderr}`. That single regression cascaded
through ~60 "failing" tests across cli, core, engine, and dashboard whose
production code was actually correct. Also relax the AI-CLI blocklist for
cheap introspection (--version/--help/which …), give SIGTERM'd subprocesses a
brief grace period before being flagged as "left running", fix a few real
test-side bugs uncovered along the way (executor mock step transitions, iOS
last-resort keyboard path, mission SSE replay tests racing with the real AI
agent), and convert dashboard route tests' dynamic `await import("../server.js")`
to static imports so first-test timings drop from 2–5s to <200ms.

Introduce a shared test-utils module and global vitest setup that
guarantee tests never write to the real .fusion directory or leak temp
directories under /tmp.
Infrastructure:
- packages/core/src/__test-utils__/workspace.ts — tempWorkspace(),
useIsolatedCwd(), trackForCleanup(), assertOutsideRealFusion() with
auto-cleanup in afterEach.
- packages/core/src/__test-utils__/vitest-setup.ts — per-worker guard:
chdirs each worker into an isolated tmp dir, wraps process.chdir to
refuse the real .fusion, scopes tmp dirs under fusion-test-workers/
(skips cwd change in thread-pool workers where chdir isn't supported).
- packages/core/src/__test-utils__/vitest-teardown.ts — globalSetup
hook that wipes the shared parent even when workers are SIGKILLed.
- scripts/check-test-isolation.mjs + `test:isolated` / `test:check-
isolation` scripts for CI.
- @fusion/test-utils alias + setupFiles + globalSetup wired into core,
cli, engine, dashboard, tui vitest configs; matching tsconfig paths.
Test refactors (no behavior change):
- cli provider-settings, auth-paths, provider-auth — switch leaking
mkdtempSync calls to tempWorkspace().
- core migration, first-run, store-backward-compat — replace manual
process.chdir save/restore with useIsolatedCwd().
- tui fusion-context — replace 9 hardcoded tmp paths (collision-prone
under parallelism) with tempWorkspace().
- dashboard useTheme, FileBrowser, TaskCard — resolve source-file reads
against a PACKAGE_ROOT computed from import.meta.url instead of cwd,
so tests don't depend on the process working directory.
Verified: full suite (~15,500 tests across 8 packages + plugins) passes
and the orphan-detector reports zero leaked temp directories after a
complete run.
