[Codex][CLI] Show model-capacity guidance on 429 (#10118)
###### Problem
Users get generic 429s with no guidance when a model is at capacity.
###### Solution
Detect model-cap headers, surface a clear “try a different model”
message, and keep behavior non‑intrusive (no auto‑switch).
###### Scope
CLI/TUI only; protocol + error mapping updated to carry model‑cap info.
###### Tests
      - just fmt
      - cargo test -p codex-tui
- cargo test -p codex-core --lib
shell_snapshot::tests::try_new_creates_and_deletes_snapshot_file --
--nocapture (ran in isolated env)
      - validate local build with backend

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.
