# NanoClaw needs `signal-cli` on PATH to talk to Signal. Picks the right
# install method per platform:
#   macOS  → `brew install signal-cli` (bottled, no Java needed)
#   Linux  → download latest native binary from GitHub releases to
#            ~/.local/bin/signal-cli (no Java, no sudo)
#
# Emits the standard NanoClaw STATUS block on success or failure so the
# `runQuietChild` driver can parse the outcome.
