Subject: [PATCH 1/6] test(helpers): load each migrated sqlite database from an
 image

Most suites build a fresh database per test and replayed every migration
each time, about 100 ms per database. Replay each migration list once per
file and deserialize the image after that. Node before 24.16 has no
serialize, so it keeps the replay.

Subject: [PATCH 2/6] test: delete tests that restate source, copy, or config

These files read source or docs and grep the text, assert copy and
markup, restate constant tables, or repeat another file's coverage.
None of them can catch a behaviour bug that typecheck, lint, or a
remaining test would miss.

From 96f5f79bb7fab23d1742fffd0e6a2a015bd98bd7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/6] test: boot Nuxt only for tests that need it

Every file booted a Nuxt app, though about 40 of 377 use it. The default
environment is now node. Files that mount components or read Nuxt
runtime config carry the .nuxt.test.ts suffix, so defineVitestConfig
runs them in its nuxt project.

The node project runs in vmThreads and drops the @nuxt/test-utils setup
file, which loaded Vue and its compiler in every file. Workers now follow
the CPU quota: 2 workers under the 4-CPU CI quota left half of it idle.

Also removes single cases that grep source, assert copy or class names,
or restate constant tables, and the node environment pragmas that now
repeat the default.
