fix(ts): TypeScript 6.0 compat — ignoreDeprecations for baseUrl + node types

TS 6.0.3 turns the `baseUrl` deprecation into a hard error (TS5101) and
stops auto-including @types/node ambient globals for the src project, so
test files using fs/path/__dirname fail (TS2591/TS2304).

- add `"ignoreDeprecations": "6.0"` to silence the baseUrl deprecation
- add `"types": ["node"]` so node module/global types resolve
  (vite/client stays covered by the /// reference in vite-env.d.ts)

`npm run gate` (tsc --noEmit && build && vitest) green: 79 files,
1107 passed / 3 skipped.
