v0.5.1

Remote control on Windows follows the viewer's pointer

• Remote control (COMPUTER_USE_REMOTE_CONTROL=1) on Windows moves the real cursor at once. It used to glide there over half a second on every hover, click, right_click and drag. A viewer streaming pointer moves (MT Code's Computer View) therefore saw the cursor lag and queue up, and frames stalled behind the moves. A hover now takes under 10 ms instead of about 500 ms, lands on the exact pixel, and works on secondary monitors (the old path could only reach the primary screen).
• screenshot takes an optional JPEG quality (1–100, default 55 as before) on Windows and Linux, so a live viewer can trade bandwidth for sharper text.

Background mode, the default, is unchanged. 32 tools; no extension changes are needed beyond 0.5.0.
