v1.6.1

Fixed

• operator-shell: a bare-shell core (via the ~/.local/bin/core PATH symlink)
  no longer goes stale after a /plugin update. The symlink previously pointed
  at ${CLAUDE_PLUGIN_ROOT}/scripts/core in the version-pinned plugin cache,
  frozen at the last /anton-core:setup; an update rotated the cache but nothing
  repointed the symlink, so the shell silently ran the binary current at setup
  time. Setup now installs a minimal self-locating launcher (shipped
  scripts/core-shim.sh) into the stable data dir at data/bin/core and points
  ~/.local/bin/core at it; the launcher execs the self-update system's live
  data/versions/current pointer, which the orchestrator repoints on every
  applied update — so the operator entry stays live with no further refresh.
  Setup materializes current (via the read-only core update status, which
  triggers the existing legacy→versioned migration) before installing the
  launcher, and uninstall removes the symlink only when it points at the
  launcher. Adds a /health operator_launcher panel that verifies the whole
  ~/.local/bin/core → launcher → versions/current → binary chain and warns
  when the symlink resolves anywhere other than the launcher, when the launcher
  file is missing, or when versions/current does not resolve to an
  executable, plus a core --launcher-check diagnostic.
