build: add a browser-test exclusion check and a pre-push static-check hook

npm run check:browser-excludes finds tests that import a browser driver and
asks `vitest list` whether the CI config still collects them; wired into CI.
npm install now also installs a marker-owned pre-push hook that runs the
static CI checks (~15s). Skip with CODEMAN_SKIP_PREPUSH=1; hand-written
hooks are left alone.

 **Code style**: Prettier (`singleQuote: true`, `printWidth: 120`, `trailingComma: "es5"`) — config lives in the **`"prettier"` key of `package.json`**, not a `.prettierrc` (keeps the repo root short; editors read it natively). `.prettierignore` stays at the root because Prettier resolves it relative to cwd. ESLint flat config (`config/eslint.config.js`) allows `no-console`, warns on `@typescript-eslint/no-explicit-any`. Ignores: `app.js`, `scripts/**/*.mjs`, `src/web/public/vendor/**`, `scripts/remotion/**`.
