v0.27.1

`peppy repo show` now reports each pairing slot a node declares alongside the indexed nodes that could fill it.

Released on September 1, 2026

peppy repo show <node>:<tag> now ends with one section per pairing slot the node declares, listing the indexed nodes that could fill it by playing the pairing's other role, and saying so when none can.
The --json output of peppy repo show now carries a pairing_slots array in each report, each entry giving the slot's link_id, pairing, role, optional, and the peers that could fill it.
