Codex CLI 0.137.0

User-facing

• [changed] codex plugin list now accepts --json and --available.

Internal / groundwork

• Added new cloud-config and prompts crates; removed cloud-requirements.
• Added a remote-control subsystem (auth, clients, request processing), cloud-config loading and caching, plugin discovery, multi-agent follow-up tasks, and rollout compression.
• Added environment variables including CODEX_ESCALATE_SOCKET and CODEX_SNAPSHOT_PROXY_OVERRIDE.
• Expanded the internal data model with new types for app config, cloud-config bundles, remote-control payloads, filesystem operations, threads, and model info; removed the assign-task and cloud-requirements types.
• Moved the review and permissions prompt logic into the new prompts crate (removing the standalone review_prompt.md).
• AGENTS.md expanded with model-context rules, a breaking-change review checklist, integration-test requirements, 800-line change guidance, test-module conventions, and a Python 3+ note.
• docs/codex-rs/bazel.md updated with BuildBuddy/local/remote execution sections.
• version.json bumped to 0.137.0.

Upgrade notes

• Integrators should review the app-server protocol additions for remote-control and permissions request types.
