* 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.

* Add local OpenAI-compatible model discovery to /model
* Guard local OpenAI model discovery from Codex routing
* Preserve remote OpenAI Codex alias behavior
On Windows, shells can set OPENAI_BASE_URL to the literal string
"undefined" when the variable is referenced without quotes while unset.
The nullish-coalescing operator (??) does not catch this because
"undefined" is a truthy string, causing resolveProviderRequest() to
treat it as a real base URL. This broke the Codex transport check:
(!rawBaseUrl && isCodexAlias(model)) evaluated as (false || true) = false
so the transport was incorrectly set to chat_completions (issue #336).
Fix: introduce asEnvUrl() which trims the value and rejects both empty
strings and the sentinel string "undefined". Use it for all three
rawBaseUrl sources (options.baseUrl, OPENAI_BASE_URL, OPENAI_API_BASE).
Tests: add three new cases to the 'Codex provider config' describe block
covering the empty-string, "undefined"-string, and options-override
scenarios. Also add beforeEach/afterEach guards so individual tests
cannot contaminate each other via env var state.
