[Bug]: Codex's command activity displays shell-wrapper quoting instead of the executed command

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. Open any project in T3 Code using the Codex provider.
2. Ask Codex to run this exact command:

pwd && rg --files -g 'AGENTS.md' -g '!node_modules'

3. Wait for the command to complete successfully.
4. Expand the command activity row.
5. Copy the displayed command and run it in zsh.

The copied command contains altered quoting around !node_modules and fails with a zsh error. The command originally submitted to the shell succeeds.

Expected behavior

The command activity row should display the exact command Codex executed. Copying it should produce a valid command with the original quoting preserved.

Here I tested it using the Claude provider, it shows correctly:

Actual behavior

The command runs successfully, but the activity row displays the shell launcher's escaped version instead of the command Codex executed. Single-quoted arguments are altered, so copying the displayed text produces an invalid command that fails in zsh.

Here I tested it using the Codex provider with the same prompt, it produced '"'!node_modules'"':

Impact

Cosmetic issue

Workaround

No response

Start in apps/web by tracing the Codex command-activity rendering and compare the displayed command with the command submitted to the shell. Reproduce with the provided pwd and rg command in zsh; done means the activity row preserves the original quoting and the copied command runs successfully.
