Drive input automation from standard input

[botoddly]

Lets an external process, such as an LLM agent running one shell command at a time, drive a Pixely app through IInputAutomation with a text protocol on standard input.

• InputAutomationCommandInterpreter runs one line (mouse move 320 180, key press LeftCtrl, text hello, ...) against IInputAutomation and answers ok, or error: <reason> for a malformed line. Handler exceptions propagate like real input.
• InputAutomationConsole reads lines on a background thread and runs those queued before the frame on the frame loop at the new UpdateOrders.Input (-10 000), one reply line per command on standard output. The per-frame drain is bounded to what was queued at frame start.
• AddInputAutomation() registers the console; it reads raw standard input so terminal mode is never changed.
• Docs: command table and a tail -f commands.txt | app > replies.txt recipe in docs/input-automation.md, new row in docs/frame-order.md.
• Tests for the interpreter (dispatch, malformed lines, propagation) and the console (order, calling thread, replies). Registration through PixelyAppBuilder is not unit tested because Build() creates the GPU device; verified with a manual run of the Hotbar tutorial.
