Auspex 0.2.0

Fixed

• A departing MCP peer can no longer take Auspex down with it. Adopting
  agent-session-kit 0.6.3 sets SO_NOSIGPIPE on every MCP socket descriptor,
  so a client that vanishes between poll and write now fails the write with
  EPIPE and runs the ordinary teardown path. Before this, the same race
  raised SIGPIPE and killed the process with no crash report — the shape of
  a long-running server that is simply gone the next time you look.
• AntiGravity turns written by agy ~1.1.18 are dated again. Those builds
  replaced the per-turn wall clock with an elapsed offset; the kit resolves it
  against the trajectory's own start time.

Changed

• agent-session-kit moves to 0.7.0, which splits the kit into peer Swift and
  Rust implementation lanes and adds a contracts/ directory holding the facts
  both must honour. Every product name, import, and pin form is unchanged for
  this package — the move is invisible here apart from the version.
