Linux packages: migrate /etc/boundary.d to /etc/threshold.d without clobbering, reuse the boundary service user, carry over service enablement with a boundary.service alias, provide a boundary command. Docker: accept /boundary/config.hcl, boundary command, /boundary symlink. CLI: deprecation notice when invoked as boundary (stderr only). Dev mode: also create *.threshold.dev aliases.
