docs(agents): address Copilot review on AGENTS.md tooling bullets

- Drop `builds/*/build.ts` from the Bun-native scope (no such file exists;
  only `tools/build.ts` does).
- Rename `node:fs/promises.glob` to "the `glob` export from
  `node:fs/promises`" so the API path is unambiguous.
- Switch Playwright CLI from the nonexistent `@playwright/cli` to the
  repo's actual `playwright` dependency: `bunx playwright <cmd>`.
