fix(ai,coding-agent): remove "(legacy)" marker from OpenAI Codex provider name

packages/ai/CHANGELOG.md

@@ -8,6 +8,10 @@
 - Added `StreamOptions.disableContinuation`, which keeps a request from using or replacing server-side continuation state such as Anthropic message threads. Set it on requests that repeat an earlier one, such as cache warming ([#11545](https://github.com/earendil-works/pi/pull/11545))
 - Added `@earendil-works/pi-ai/lazy-oauth` (`registerLazyOAuthFlows()`) and `@earendil-works/pi-ai/lazy-bedrock-provider` (`registerLazyBedrockProvider()`, built on the new `setBedrockProviderLoader()`) for Node bundles that split at dynamic imports: the OAuth login flows and Bedrock load through literal dynamic imports, so the bundler keeps them inside the bundle as chunks that load on first use, instead of through the variable-specifier imports that load pi-ai's own files at runtime. Nothing changes without calling them.
 
+### Changed
+
+- Renamed the "OpenAI Codex (legacy)" provider back to "OpenAI Codex"

 ### Fixed
 
 - Fixed tool arguments for `Type.BigInt()` and `Type.Undefined()` parameters being rejected: they convert as TypeBox converted them (`"42"` and `42` to `42n`, `null` to `undefined`), now that pi-schema supports both types. `Type.Void()` still rejects every JSON argument.

 Provider notes:
 
-**OpenAI Codex (legacy)**: Superseded by Sign in with ChatGPT on the OpenAI provider. Requires a ChatGPT Plus or Pro subscription. Provides access to GPT-5.x Codex models with extended context windows and reasoning capabilities. The library automatically handles session-based prompt caching when `sessionId` is provided in stream options unless `cacheRetention` is `"none"`. You can set `transport` in stream options to `"sse"`, `"websocket"`, or `"auto"` for Codex Responses transport selection. When using WebSocket with a `sessionId` and cache retention enabled, connections are reused per session and expire after 5 minutes of inactivity. Call `cleanupSessionResources(sessionId)` when finished so the pooled connection does not keep the process alive.

 **Azure OpenAI (Responses)**: Uses the Responses API only. Set `AZURE_OPENAI_API_KEY` and either `AZURE_OPENAI_BASE_URL` or `AZURE_OPENAI_RESOURCE_NAME`. `AZURE_OPENAI_BASE_URL` supports both `https://<resource>.openai.azure.com` and `https://<resource>.cognitiveservices.azure.com`; root endpoints are normalized to `.../openai/v1` automatically. Use `AZURE_OPENAI_API_VERSION` (defaults to `v1`) to override the API version if needed. Deployment names are treated as model IDs by default, override with `azureDeploymentName` or `AZURE_OPENAI_DEPLOYMENT_NAME_MAP` using comma-separated `model-id=deployment` pairs (for example `gpt-4o-mini=my-deployment,gpt-4o=prod`). Legacy deployment-based URLs are intentionally unsupported.
