Add a $PATH lookup as a third option in tool_path(), so the resolution becomes:

TX3_{NAME}_PATH env var (unchanged)
Search $PATH for the tool (new — higher priority than hardcoded dir)
~/.tx3/default/bin/{name} (unchanged, now last resort)

This way, if a user has tx3c on their PATH (e.g. via nix shell), it takes precedence over whatever is in ~/.tx3/default/bin/.
