v1.14.0

v1.14.0

Features

• Codex config guard: new model context parameters: add built-in managed
  parameters for model_context_window and model_auto_compact_token_limit
  in ~/.codex/config.toml.

Fixes

• Custom guard parameter payload: rename applyMode/valueType to
  apply_mode/value_type when adding custom parameters so the frontend
  payload matches the Rust schema. Update the smoke install mock and unit
  test accordingly.

Verification

• pnpm run build passes.
• pnpm exec vitest run passes.
