Codex doctor report

What issue are you seeing?

When starting Codex in an untrusted directory and selecting the option to
trust the directory, the TUI shows only:

Failed to set trust for <my_cwd_path>: config/batchWrite failed in TUI

This message is not actionable because it hides the underlying app-server/
config error. The failed operation is trying to persist project trust to the
user config, equivalent to:

[projects."<my_cwd_path>"]
trust_level = "trusted"

What steps can reproduce the bug?

1. Start Codex in a directory that is not already trusted, for example:

   cd <my_cwd_path>
   codex

2. At the TUI trust prompt, select the option to trust/continue.

3. Observe the error:

   Failed to set trust for <my_cwd_path>: config/batchWrite failed in TUI

What is the expected behavior?

The TUI should include the underlying config/batchWrite server error, for
example:

Failed to set trust for <my_cwd_path>: config/batchWrite failed in TUI:

or otherwise surface the JSON-RPC error message/data so the user can
distinguish readonly config, invalid config, app-server failure, and
validation failures.
