chore(v1): raise Node floor to >=22 and add codeman bin alias

- engines.node >=18 -> >=22 (Node 18/20 are EOL; CI only tests 22; the start script + systemd unit use NODE_COMPILE_CACHE which needs 22.1+). Updates the README badge and CLAUDE.md requirements to match.
- bin: add a 'codeman' alias alongside 'aicodeman' so 'npm i -g aicodeman' provides the 'codeman' command every doc/symlink references (program.name is already 'codeman'; the published package name stays 'aicodeman').
