pnpm --dir playground test:e2e:sw:all was always red: its last suite, sw-node, ran e2e-sw/subpath.spec.ts.

Root cause: a config match, not a node-server bug. subpath.spec.ts (added in 2670f4c) needs a render: "spa" build under --base /app/, served by e2e-sw/subpath-host.ts; it has its own config, playwright.sw-subpath.config.ts. When it landed, playwright.sw.config.ts and playwright.sw-spa.config.ts got subpath.spec.ts in their testIgnore; playwright.sw-node.config.ts did not. So sw-node ran it against an ssr build rooted at /, where every /app/ URL is outside the app. All 13 failures on main are in that spec; every other spec in sw-node passed.

Change: playwright.sw-node.config.ts adds subpath.spec.ts to testIgnore, the same way its siblings do. The spec still runs where it can pass, in test:e2e:sw:subpath.

Reproduce (main):

pnpm build && pnpm playground:setup
pnpm --dir playground test:e2e:sw:node
# 13 failed (all e2e-sw/subpath.spec.ts, chromium + webkit), 20 skipped, 45 passed

Verify (this branch):

pnpm --dir playground test:e2e:sw:all   # exit 0
# sw         47 passed, 19 skipped
# sw-spa     55 passed, 11 skipped
# sw-prompt   2 passed
# sw-subpath 13 passed, 1 skipped
# sw-node    45 passed, 19 skipped
pnpm --dir playground exec biome check playwright.sw-node.config.ts
pnpm --dir playground exec tsc --noEmit -p .

Tested on: Linux (WSL2), Node 22, chromium + webkit (Playwright's iPhone 13 device), every suite in test:e2e:sw:all.
Not tested: CI. No workflow runs sw-node or sw-subpath today, and this PR leaves the workflows alone.
