diting v0.8.3

Slider CAPTCHAs, the deterministic media pipeline, and a skill-side
jurisdiction clarification.

Engine:

• pointer capture: Element.setPointerCapture / releasePointerCapture /
  hasPointerCapture with a capture registry and got/lostpointercapture
  events. Drag-slider CAPTCHAs (the "hold the slider and drag it to the
  right" wall) call setPointerCapture in their pointerdown handler and
  track pointermove on the handle itself — the API being absent made the
  handler throw at the press, so sliders could not be dragged at all.
  The session/CDP mouse chains now honor capture: while a pointer is
  captured, moves and the release dispatch to the captured element with
  real coordinates, and pointerup releases as Chrome does implicitly.

Media pipeline (authored HTML in, fixed bytes out):

• /screenshot {html}: literal HTML renders straight to PNG — no URL, no
  robots check, no network
• /video {html}: CSS keyframe animations (or window.__timelines JS
  orchestrations) render frame-by-frame through a virtual clock into an
  MP4 — same input, same bytes
• /render layout family: cover (WeChat-crop-safe square 1024x1024 and
  wide 1080x460 with a dashed crop guide), card (square with
  accent-spined body rows), title (vertical 1080x1920 opener frame)

Session:

• snapshots pierce open shadow DOM — ref=eN coverage completes on
  componentized sites

Skill:

• tool-jurisdiction note: another tool's site policy governs that tool,
  not diting — a user instruction to open a site in diting is not
  overridden by a different tool's refusal
