The gateway approval system previously intercepted bare 'yes'/'no' text
from the user's next message to approve/deny dangerous commands. This was
fragile and dangerous — if the agent asked a clarify question and the user
said 'yes' to answer it, the gateway would execute the pending dangerous
command instead. (Fixes#1888)
Changes:
- Remove bare text matching ('yes', 'y', 'approve', 'ok', etc.) from
_handle_message approval check
- Add /approve and /deny as gateway-only slash commands in the command
registry
- /approve supports scoping: /approve (one-time), /approve session,
/approve always (permanent)
- Add 5-minute timeout for stale approvals
- Gateway appends structured instructions to the agent response when a
dangerous command is pending, telling the user exactly how to respond
- 9 tests covering approve, deny, timeout, scoping, and verification
that bare 'yes' no longer triggers execution
