**Test suites split into named lanes and CI matrix expanded to OS×Node** — `scripts/run-tests.cjs` now accepts `--suite <unit|integration|install|security|slow|all>` and filters by filename suffix (`*.security.test.cjs`, `*.integration.test.cjs`, etc.). New package scripts `test:unit`, `test:integration`, `test:install`, `test:security`, `test:slow`, `test:coverage:unit`, and `test:coverage:all` give callers stable entrypoints; `npm test` and `npm run test:coverage` keep their original behavior (full sweep). CI matrix grew from `ubuntu × {22, 24}` + a single macOS lane to `{ubuntu, macos, windows} × {22, 24, 26}` with Node 26 in `continue-on-error` until `actions/setup-node` stabilises it. `fail-fast: false` so a single lane failure no longer cancels the rest. Install and slow suites only run on `main` push to keep PR CI fast; a dedicated `coverage` job runs `test:coverage:unit` on ubuntu/Node 24 and uploads the report. New grouping policy documented in `docs/TESTING-SUITES.md`. Closes #3597.

**`scripts/run-tests.cjs` no longer fails on Windows when invoking many test files at once** — Windows `CreateProcess` caps `lpCommandLine` at 32,767 chars, so an unchunked spawn of `node --test <546 paths>` aborted instantly with exit 1 and no test output (Linux/macOS allow ~2 MB so the same path worked there). The harness now batches selected files into chunks whose total argv stays under 28,000 chars and runs each chunk sequentially, reporting `run-tests: chunk N/M — K files` to stderr. The ceiling is overridable via `RUN_TESTS_MAX_CMDLINE_CHARS` for tuning and tests. Adds a cross-platform regression test that forces chunking with a low ceiling.
