Dylan Hurd 67afc79674 Use ReviewDecision for MCP tool approvals (#38081)
## What changed

- Add `ApprovedMcpPolicyAmendment` to represent MCP approvals that persist across sessions.
- Route MCP approval responses directly through the shared `ReviewDecision` type while preserving session-only approvals, rejection reasons, timeouts, and cancellations.
- Reject the MCP-only policy decision if it reaches command, shell, network, or other tool approval paths.

## Testing

- Update MCP approval parsing, normalization, hook, and Guardian tests for the shared decisions.
- Verify generic tool approvals reject MCP policy amendments.

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.
