test: switch integration project to folder-based manifest (#1314) (#1318)

* test: switch integration project to folder-based manifest (#1314)

Replace the `integrationTests` enumeration in vite.config.ts with a
folder glob (`src/test/integration/**/*.test.ts`). Files under that
folder run in the integration vitest project (node env, 30s timeouts);
everything else runs in the unit project (happy-dom).

This removes the silent misclassification trap from #1307: a new
integration-style test no longer falls into the unit project (and
happy-dom) just because someone forgot to add it to the array.

The 13 ported v1.5 tests + their helpers move under src/test/integration/
in a strict mirror of core/ source layout (mcp/, auth/, auth/node/,
storage/). Renames use git mv so history is preserved.

* test: address PR review on #1318 (glob extensions + AGENTS doc)

- vite.config.ts: widen integrationGlob from `*.test.ts` to
  `*.test.{ts,tsx}` so the integration folder fully owns its contents.
  Without this, a `.test.tsx` placed under src/test/integration/ would
  match the unit project's `{ts,tsx}` include, fail the unit `.ts`-only
  exclude, and silently land under happy-dom — the exact misclassification
  trap this PR set out to close.
- AGENTS.md: update the line describing where integration tests live;
  it still pointed at the old `src/test/core/` location and the removed
  `integrationTests` enumeration.
