Previously the Pending Peer Requests panel only had Approve/Reject for
inbound rows; outbound rows in the 'sent' state had no action and
would sit there until the target explicitly approved or rejected. Now
you can Cancel an outbound request — the local row is dropped and a
PeerCancel nostr DM is sent so the target's inbound row also
disappears.
Backend:
- HandshakeMessage::PeerCancel {reason: Option<String>} variant.
- nostr_handshake::send_peer_cancel() mirrors send_peer_reject.
- handshake.poll handler dispatches inbound PeerCancel: finds the
matching inbound pending row (same from_nostr_pubkey, state=Pending)
and deletes it. Reply shape gains `cancelled_inbound: [id]`.
- federation::pending::delete() — hard-remove (set_state only
transitions; we don't want 'Cancelled' ghosts in the audit trail).
- federation.cancel-request RPC: outbound+Sent only, default
notify=true (cancelling silently is a footgun), best-effort DM
(relay failure doesn't block local deletion). Wired in dispatcher.
Frontend:
- PendingRequestsPanel.vue: Cancel button appears only on
outbound+sent rows. Emits 'cancel' event with request id.
- Federation.vue: cancelPending(id) handler calls
rpcClient.federationCancelRequest and reloads the list.
- rpcClient.federationCancelRequest(id, reason?, notify=true).
