KellyMichels c0d5708ad6 fix(bash): make the port bash-3.2 / BSD-clean so it runs on stock macOS

The README advertises macOS support, but the port used constructs that
fail on the userland macOS actually ships:

- `mapfile` (bash 4+) in 10 spots — macOS ships bash 3.2 as /usr/bin/bash,
  so a mac user following the README hit "mapfile: command not found" and
  silently got empty project lists. Replace each with a portable
  `while IFS= read -r` loop (identical arrays; set -u safe on empty input).
- `_z_commafy` used the GNU-only `sed :a;...;ta` label/branch idiom, which
  errors on BSD/macOS sed (the token footer's thousands separators).
  Reimplement with awk (already a dependency).
- README: correct the macOS line — bash 4+ does NOT ship with macOS; the
  stock 3.2 now works, and only jq needs brew.

Also two correctness nits found in the same review:
- zkill/zrestart `--kill-all` was parsed but silently ignored; now it
  prints a "not implemented in the bash port" notice instead of no-op.
- zrepair's smoke-test line said "https://$domain" but probes
  http://$HOST with a Host header; label now matches what it does.

Verified on WSL (bash 5): read-loops produce the same 11 project / 7
domain keys as mapfile; awk commafy matches across 0..1,234,567; empty
producer yields a 0-length array; footer renders. 3.2-compat is by static
analysis — no bash-4-only constructs remain.

Token Savers — bash port (Linux / macOS / WSL)

Native bash versions of the z-scripts. Same commands, same zconfig.json schema, same behavior — no PowerShell required.

Requirements

bash 3.2+ (the stock macOS bash works), jq, curl, zip, OpenSSH (ssh/scp)
lsof (for zkill/zrestart), rsync (for zsync <project> mirror mode)
Docker + docker compose on the remote host for the deploy scripts

Debian/Ubuntu: sudo apt install jq curl zip lsof rsync macOS: brew install jq (bash, curl, zip, ssh, lsof and rsync already ship with macOS)

Install

git clone https://github.com/kellymichels/zscripts-token-savers.git ~/zscripts
cd ~/zscripts/bash
cp zconfig.example.json zconfig.json   # then fill in your values
chmod +x z* setup_backup_schedule
echo 'export PATH="$HOME/zscripts/bash:$PATH"' >> ~/.bashrc && source ~/.bashrc

Commands

Same set as the PowerShell versions — the project key in zconfig.json IS the command argument:

Command	What it does
`zstart <p> [--detached]`	start local dev server (python/vite/nextjs)
`zkill <p>`	free the project's dev port
`zrestart <p> [--detached]`	kill + start in one command
`zstop <p>`	stop the project's compose stack on the server
`zdeploy <p> [--note "msg"]`	zip → scp → docker compose build/up → verify build version
`zec2 [<p>]`	TCP + HTTP + live-version reachability check
`zec2online [<p>]`	deep health check; auto-starts downed stacks
`zrepair <p>`	audit/repair container + proxy routing, smoke test
`zbackup [<p>] [--tag t]`	local source zip (+ pg_dump when .env has DATABASE_URL)
`zbackup_ec2 [<p>]`	pull db dump + data dirs down from the server
`zsync`	copy new backup files offsite (never overwrites)
`zbackup_and_sync`	both of the above; cron-friendly
`setup_backup_schedule --install`	daily backup cron job
`zsetup_mail --domain d`	provision docker-mailserver mailboxes + print DNS records
`zstart_docker`	bring up the local compose stack in `bash/docker/`

Flags use GNU style (--port 3000, --detached) instead of PowerShell style (-Port, -Detached). Detached dev servers log to /tmp/zstart-<project>.log.

Usage tracking

Every run prints a footer with its own output volume:

--- 1,048 lines / 69,009 chars / ~19,717 tokens est. (Claude Code) ---

and (when jq is available) appends one JSON line per run to tokens.jsonl, so you can see how much infrastructure output you keep out of an AI agent's context over time. Fields: ts, script, projects, lines, chars, est, model (est ≈ chars / 3.5). Nested runs (the zkill/zstart inside zrestart) are counted once, not double.

Where it's written, first match wins:

$ZTOKENS_DATA
ztokens.dataDir in zconfig.json
the sibling ../ztokens/data directory, if present
~/.ztokens/data (created on first run)

Set ZTOKENS_MODEL to tag records with a specific model; it defaults to est. chars/3.5.

Differences from the PowerShell versions

zsync <viteproject> mirrors dist/ with rsync -a --delete (robocopy /MIR equivalent).
Scheduling uses cron (setup_backup_schedule) instead of Windows Task Scheduler.
The MOTD banner picks a random motd/*.txt instead of tracking a shuffle rotation.
Windows-only helpers (.cmd launchers) don't exist — scripts are directly executable.
