What issue are you seeing?

What happened?

Codex CLI honors reasoning-effort settings from ~/.codex/config.toml, but Codex Desktop / app wrapper appears to ignore them.

Config

~/.codex/config.toml:

model_reasoning_effort = "medium"
plan_mode_reasoning_effort = "high"

### What steps can reproduce the bug?

Set the config.toml properties as described, manually set the resoning effort to Low and then enter /plan.

### What is the expected behavior?

The reasoning effort should be updated to High on the Codex App.
