lmcp.lua: if opts.auth_token and opts.conf are both unset, fall back to
the LMCP_TOKEN environment variable. Empty string treated as unset.
This is the primitive launchd/systemd drop-ins need — no conf file
bookkeeping on hosts that don't already use one.
scripts/lmcp-install-macos.sh: macOS installer via Homebrew. Drops the
Lua library files into $(brew --prefix)/share/lua/5.4/, mints (or
reuses) a Bearer token stored at $(brew --prefix)/etc/lmcp/token,
installs a ~/Library/LaunchAgents/ plist with LMCP_TOKEN baked in,
launchctl-loads it, and smoke-tests. Prints the Claude Code ~/.claude.json
snippet at the end.
