Vanilla has no /pregen, so with it always registered /help and the command
tree differed from vanilla's (the command_exec harness failed on /help).
Horizon's own commands are now added to the game's tree only when the owner
asks: `horizon-pregen=true` in server.properties (`horizon-pregen = true`
under [properties] in server.toml) for a dedicated server, `--pregen` for
the game (single player, LAN). Off, the trees are vanilla's own, unchanged.

A Chunky-like command for single player and servers: /pregen start
<radius> [square|circle] [<x> <z>], status, pause, continue and cancel,
with progress (chunks, chunks/s, time left) in the log and to the player
who started it.
The area is swept strip by strip by a band of rows that streaming treats
like a player's area (Streaming::set_band). A row is done once its chunks
are lit and post-processed; the rows behind the band then unload and are
saved, so memory holds only the rows in flight. The band's chunks are
ranked for decoration row by row as they come within reach, so a task
decorates in the same order however its jobs are timed. Between ticks
the server waits on the workers' results and schedules the next jobs at
once instead of once a tick.
