Morning Herdr issue-desk cron

Unattended daily issue pass: a user-session terminal multiplexer (Herdr) is already running. Cron only talks to that socket.

• Morning: start or nudge a manager agent on the main checkout. Manager does not implement on main.
• Manager writes a dated run folder (queue, workers, summary) on disk; leave tabs/workspaces open for human review.
• Children: one isolated git worktree + one agent each. Cap concurrency (default 3).
• Nightly: if the manager is still live, ask it for a wrap file. Do not spawn a second evening manager.
• Timers are code in the repo (crontab snippet + systemd user units + install script). Re-run install on a new machine.
• If the multiplexer socket is missing, the cron job exits 0 and logs a skip.
• Never auto-merge release-please PRs.

Why: overnight GitHub triage without mixing work onto main. How to apply: install the repo's issue-desk script; review the latest run folder and open workspaces in the morning.
