test(snap): pin oxlint ignorePatterns + nested-config behavior

Documents two behaviors observed while investigating why `vp lint` at
the repo root was leaking snap-test fixture diagnostics:

1. Root vite.config.ts `lint.ignorePatterns` (wildcard-prefixed) does
   filter files out of the lint walk when no nearer oxlint config
   exists — packages/ignored/src/index.js is skipped despite its
   console.log.
2. Nested vite.config.ts in a subpackage (packages/included/
   vite.config.ts, no-console:off) is NOT consulted when cwd is the
   workspace root; the root's no-console:error still flags it.
