fix: remove /prompt slash command — footgun via prefix expansion

/pr <anything> silently resolved to /prompt via the shortest-match
tiebreaker in prefix expansion, permanently overwriting the system
prompt and persisting to config. The command's functionality (setting
agent.system_prompt) is available via config.yaml and /personality
covers the common use case.

Removes: CommandDef, dispatch branch, _handle_prompt_command handler,
docs references, and updates subcommand extraction test.

+- `/skin`, `/tools`, `/toolsets`, `/browser`, `/config`, `/cron`, `/skills`, `/platforms`, `/paste`, `/statusbar`, and `/plugins` are **CLI-only** commands.
 - `/verbose` is **CLI-only by default**, but can be enabled for messaging platforms by setting `display.tool_progress_command: true` in `config.yaml`. When enabled, it cycles the `display.tool_progress` mode and saves to config.
 - `/status`, `/sethome`, `/update`, `/approve`, `/deny`, and `/commands` are **messaging-only** commands.
