wait-for screen NAME|widget ID|loaded|chat TEXT|event KIND replies once
the game gets there (--timeout, default 30 s, ends in an error of kind
timeout; --since SEQ counts chat and events from an earlier point), so
scripts and agents stop polling. events [--since SEQ] lists what
happened, oldest first, numbered: screens, chat lines, deaths, respawns,
items gained or lost, dimensions, worlds opened and closed. The state is
compared once per event loop turn and only under --control, so watching
never changes the game. respawn now says when the death screen's button
is not active yet instead of clicking it to no effect.
horizon-ctl and its MCP gain both; tools/agent_control_e2e.py gains an
events scenario.

options-get [KEY...] gives every options.txt option by its vanilla key
with its value and what it accepts (type, range, step or choices; enums
by name, key bindings as key.keyboard.w). options-set KEY VALUE sets one,
applies it at once and saves options.txt as the options screen does
(language and resource packs reload too); a value the option refuses is
an error naming what it accepts, and the option keeps its value. After a
set, ui reads the redrawn screen.
horizon-ctl and its MCP gain both; tools/agent_control_e2e.py gains an
options scenario.

`ui` lists every widget the last frame drew (title menus, pause, options
in both menu styles, inventories and menus) with an id, its kind, label,
bounds and value; `click ID` clicks one through the same window events
as the mouse, `set ID VALUE` moves a slider along its track. Ids come
from labels (FOV: 70 is fov), world/server/language rows carry their
names, Horizon switches, sliders and segments their row's caption, and
inventory slots are slot-ID with their stacks. After a click, the next
widget command waits for a redrawn frame.
horizon-ctl and its MCP gain ui, click and set, and launch --offscreen.
tools/agent_control_e2e.py gains a ui scenario and runs offscreen on
macOS; both scenarios now handle Singleplayer opening Create New World
when there are no worlds.

On a virtual screen: create a world through the title menus, walk to a tree,
break a log, craft planks in the inventory screen, place one and read it
back, once with horizon-ctl commands and once over horizon-ctl mcp.
