#   1. Async pre-warm: ensure a version-matched basemind binary is cached so the
#      first MCP tool call isn't a cold install. After the first run the launcher's
#      fast path makes this instant.
#   2. Status-line nudge: Claude Code plugins cannot set the main status line, so
#      if the user hasn't wired it yet, inject a one-line hint about /bm-statusline.
#
# Output goes to stdout as the hook's JSON result; diagnostics would go to stderr.
