chore(deps): upgrade vitest to 3.2.4, vite to 7, codspeed plugin to 5.4

Vitest 2 → 3 upgrade lets us restore @codspeed/vitest-plugin to ^5.4.0,
which is required for the plugin to enumerate individual benchmark tasks
under Vitest's runner (4.x silently emitted empty results on Vitest 2.x).

Config migrations:
- drop removed `transformMode` and `deps.registerNodeLoader` options
- replace `threads: false, isolate: false` with `pool: "threads"`
  (forks+singleFork+no-isolate accumulates all 41 test files' state in
  one Node process and OOMs at 4 GB; threads pool retains v2 semantics)

Test fix:
- `tests/createErrorBoundary.test.ts`: two assertions used `.toThrow(error)`
  with an Error instance and relied on Vitest 2's loose message-only
  matching. Vitest 3 does a structural diff, so the StatusError wrapper
  no longer satisfies an Error expectation. Tests now catch the throw
  directly and assert `caught.cause ?? caught === error`, which is what
  the test intent really was.
