0.15.0

Changed

• Agent instructions live in AGENTS.md, the convention shared across
  AI coding tools, instead of CLAUDE.md. CLAUDE.md and
  CLAUDE.local.md are gitignored for personal notes (Sam's suggestion
  in #51). Claude Code 2.1.277 or later reads AGENTS.md natively.

Fixed

• Topology: a filter toggle no longer re-flows the map (#52, from
  Sam / @slmingol). Every toggle restarts the simulation, and on a map
  without saved positions that moved every node the operator hadn't
  dragged — by a hundred pixels or more for core only. Now the first
  settle is the arrangement: the nodes that took part in it are held where
  they landed, and a node a toggle reveals later flows into the gaps
  between them. Drag still pins and saves, shift-click frees, reload
  re-settles. A map whose nodes all carry saved positions is unchanged.

• pfSense: a 404 note says which kind of absence it is (#51, from
  Sam / @slmingol). The OpenVPN and IPsec status endpoints also answer 404
  when that feature is not configured on the firewall, pfrest installed
  and current, and the old note sent operators after the package. Those
  two calls are optional now and their note names the feature; a core
  endpoint's 404 still means pfrest is missing or too old, and says so.
