setup: auto-install signal-cli when missing

Browse Source 
When a user picks Signal in setup and signal-cli isn't on PATH, today
NanoClaw bails with a GitHub releases link and tells them to re-run.
That's a hard wall for non-technical users — GitHub releases pages
are intimidating, and the Linux native build / Java decision isn't
obvious.

Replace the bail-out with a real install: a new install-signal-cli.sh
script that does `brew install signal-cli` on macOS or downloads the
native Linux release into ~/.local/bin (no Java, no sudo). Wired into
ensureSignalCli with a spinner; probe again after, fall back to the
original manual-install copy if anything fails.
