Agent job kinds

Every job the panel can send to a node. The agent leases jobs one at a time per server; see the agent protocol. Unknown kinds are failed with an error.

Kind	What it does
agent.update	Download the new agent, verify its SHA-256, trial-run it, keep the old binary as .prev, swap and re-execute.
backup	Archive the server's data (from a frozen snapshot when the node uses volumes) and upload it with the signed URL.
command	Send one console command: RCON for Minecraft (queued on the console pipe while the server is starting), stdin for other games.
configure	Apply new limits to a running container, or (with recreate) remove and recreate it with new settings, ports or environment. Also resizes the data volume.
create	Create the data volume and the container for a server and start it.
delete	Remove the container, its data volume and its files.
evict	Remove this node's copy of a server that now lives elsewhere (failover); data is moved aside and kept for the configured retention.
file.delete	Delete regular files (never folders, never through symlinks).
file.download	Stream a file for download.
file.export	Send a file or folder from the server's data directory to the panel for download.
file.extract	Extract an archive inside the data directory with traversal protection.
file.fetch	Download one file for an add-on: HTTPS only, hosts listed in the job, public addresses only, SHA-512 (or SHA-256) must match, size counted against the disk allowance, placed atomically. An optional replace list removes old files only after the new one is in place.
file.import	Receive an uploaded file from the panel into the server's data directory.
file.list	List a folder in the server's data directory.
file.mkdir	Create a folder.
file.read	Read a text file for the editor.
file.rename	Rename a file; used for add-ons only to add or drop the .disabled suffix, never overwriting.
file.upload	Write an uploaded file.
file.write	Write a text file from the editor.
kill	Kill the container immediately.
logs	Return the last lines of the container log.
reinstall	Delete the server's data and container and create them again.
restart	Stop gracefully and start again.
restore	Download a backup and replace the server's files with it, staging before the swap. Can restore a backup of another server (clone, failover).
start	Start the container (re-mounting the data volume first when needed).
stop	Stop gracefully: RCON or the console pipe for Minecraft, otherwise docker stop.
verify-backup	Download a backup archive and check its integrity and safe extraction.
