rhan-oai b2aa42e6f1 Support model catalog overrides for MCP resource tool specs (#47677 )

## Why

MCP resource helpers use fixed descriptions and parameter schemas, preventing the model catalog from supplying model-specific guidance.

## What changed

Add `model_messages.tools.mcp_resources` entries for `list_mcp_resources`, `list_mcp_resource_templates`, and `read_mcp_resource`. Resolve these entries for the current model when constructing tool specs for direct calls and Code Mode.

Descriptions and parameter schemas override independently. Preserve bundled defaults for missing fields and fall back to bundled parameters with a warning when a supplied schema is invalid. MCP resource execution remains unchanged.

## Testing

Add unit coverage for independent overrides, literal descriptions, and invalid-schema fallback. Add integration coverage for resource discovery and reading through direct calls and Code Mode, plus assertions that resource tool specs follow model changes between steps.

codex-protocol

This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.

This crate should have minimal dependencies.

Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
