Provide in-app help for TUI slash commands

Product

Codex CLI / interactive TUI

Version

codex-cli 0.125.0

Problem

There is no discoverable single-step command to list all interactive TUI slash commands.

codex --help lists shell subcommands, but not the interactive slash commands. Inside the TUI, /help is unrecognized and tells the user to type /, which opens an interactive picker. That picker requires scrolling and is not easy to copy, export, or reference outside the TUI.

Reproduction

1. Run codex --no-alt-screen.
2. In the TUI, type /help and press Enter.
3. Observe: Unrecognized command '/help'. Type "/" for a list of supported commands.
4. Type /.
5. Observe: the slash command picker appears, but there is no single command that prints the full list.

Expected behavior

There should be a single-step way to view or copy all interactive TUI slash commands, for example /help, /commands, or codex commands, with descriptions.

Actual behavior

/help is unrecognized. / opens only an interactive picker.

Why this matters

Users can discover codex --help shell commands, but not all TUI-only slash commands such as /status, /fast, /feedback, /ps, /stop, /clear, and /personality.
