Closes the remaining non-broccolini interaction paths after the prior
TICKET_BUTTON_HANDLERS gate. After this commit, every bot interaction is
staff-only except the panel buttons (open_ticket / open_ticket_thread /
open_ticket_channel) and their ticket-creation modal submit — those have
to stay public because they're how members and customers open tickets.
Specific changes:
- handlers/commands/index.js: handleCommand no longer has the
`!== 'help'` carve-out. /help now goes through requireStaffRole like
every other slash command. Non-staff get the same ephemeral
"only available to the support team" reply.
- broccolini-discord.js: the signature_modal_* modal-submit handler now
calls requireStaffRole before writing to StaffSignature. /signature
already gates the modal display via the slash-command staff check;
this is defense in depth against directly crafted submissions.
- handlers/buttons.js: cancel_delete_tag moved out of
FREE_BUTTON_HANDLERS and gated alongside confirm_delete_tag::*. The
dialog is only shown ephemerally to the staff who triggered
/response delete, so non-staff can't reach it in normal flow; gating
keeps the button surface consistent.
Kept public (by design — these are the customer entry points):
open_ticket / open_ticket_thread / open_ticket_channel buttons
ticket_modal / ticket_modal_thread / ticket_modal_channel submits
