KellyMichels 8e6ffea1a4 feat(bash): native bash port of all z-scripts for Linux/macOS/WSL
Full port: zhelpers.sh library (jq config, ssh, http/tcp, archive builder,
build-version, motd, port-kill), all commands (zstart/zkill/zrestart/zstop,
zdeploy with 5 kind handlers, zec2/zec2online/zrepair, zbackup/zbackup_ec2/
zsync/zbackup_and_sync, zstart_docker, zsetup_mail, setup_backup_schedule via
cron), Unix-path zconfig.example.json, and a bash/README.md.

Verified: bash -n clean on all scripts; archive exclusions, config semantics,
and zec2 tested against the real config and live server from Git Bash. Needs a
Linux/macOS/WSL shakedown for lsof/rsync/nohup paths before merging.
