Steve Coffey f088e0c4ff Allow replacing dynamic tools between model steps (#57553)
## What changed

Add `CodexThread::replace_dynamic_tools` to replace the tool catalog without starting a turn. Updates apply to subsequent model steps and future turns while preserving in-flight calls; an empty list clears the catalog.

Require host opt-in through `allow_persistent_dynamic_tool_updates` for persistent threads. Persist replacements before publishing them, restore the latest catalog on resume, and preserve replacements and explicit clears through compaction. Keep explicit resume overrides separate from the persisted catalog.

## Testing

Add coverage for pending calls during replacement, replacement and clearing across restart, compaction recovery, resume overrides, submission ordering after caller cancellation, host opt-in, and persistence failures.

ThreadManager Sample

Small one-shot binary that starts a Codex thread with ThreadManager from codex-core-api, submits a single user turn, and prints the final assistant message.

Authentication uses the configured credential storage under CODEX_HOME, including cli_auth_credentials_store, mcp_oauth_credentials_store, and features.secret_auth_storage. Local managed authentication requirements and auth routing settings are respected. This also applies to cargo run builds. Other execution settings remain the sample's built-in configuration.

cargo run -p codex-thread-manager-sample -- "Say hello"

Use --model to override the configured default model:

cargo run -p codex-thread-manager-sample -- --model gpt-5.2 "Say hello"

The prompt can also be piped through stdin:

printf 'Say hello\n' | cargo run -p codex-thread-manager-sample
