* fix: restore Grep and Glob reliability on OpenAI paths
Preserve Grep and Glob pattern fields during OpenAI/Codex schema sanitization, and fall back to system ripgrep when the packaged binary is missing. This keeps search tool schemas intact and improves Linux usability for npm/source installs.

* test: clean up ripgrep fallback test helpers
Remove the unused ripgrepCommand import and normalize mocked builtin ripgrep paths so the test behaves consistently across platforms.

* test: remove duplicate Codex URI schema case
Drop the duplicated WebFetch URI-format test in codexShim.test.ts so test names stay unique and failures remain easier to read.

* test: stabilize ripgrep fallback coverage
Avoid fs/module mocking in ripgrep fallback tests by extracting the config selection logic into a pure helper. This preserves the fallback coverage while removing the test interaction that caused the narrowed Bun hang repro.

* test: tighten ripgrep and schema coverage
Align the ripgrep fallback test with the actual auto-fallback branch, clean up strict typing in schema sanitizer tests, and tighten ripgrep error narrowing for type safety.
