reload — herdr agent self-reload

Wake yourself (or any agent in the current pane) after a delay by typing a prompt back into the pane and pressing Enter. Useful for polling, timed follow-ups, "check again in 5 minutes", or resuming a paused workflow without a human in the loop.

How it works

1. Resolve the current pane from $HERDR_PANE_ID (fallback: herdr pane current).
2. Launch a detached background timer (nohup, or setsid on Linux) that outlives the current agent turn.
3. After the delay it runs herdr pane send-text <pane> "<prompt>" then herdr pane send-keys <pane> enter — the prompt lands in the pane's input and submits, re-prompting the idle agent.

The heavy lifting is in scripts/reload.sh, which handles pane resolution, delay parsing, and cross-platform detaching (Linux + macOS).
