feat(computer-use): raw-image fallback for text-sparse AX trees

[Tryanks]

Implements the single fallback path chosen for #123 (OCR was explicitly rejected and reverted in #257): raw-image pass-through.

• Trigger (is_text_sparse, pure/unit-tested): frame ≥ 20,000 sq screen points with < 3 descendants bearing a title/value/description (root window title excluded).
• On trigger, observe_ui marks text_sparse: true and attaches the window screenshot through the existing capture_window path and image/png content block — at most one capture per observation. The AX tree is untouched; no synthesized nodes, no new dependencies.
• imageMode: never blocks every capture (now consistently including visual/fused requests); always keeps current behavior plus the flag; auto captures only for sparse trees when Screen Recording permission is granted, degrading gracefully to the flagged plain tree otherwise.
• docs/computer-use.md deviations updated: pictureOnly resolved via raw-image pass-through by maintainer decision; Windows backend and CDP roots remain.
• Tests: 17 in-crate (trigger rule ×3, mode/permission matrix); full workspace suite green.

Part of #123 (Windows/UIAutomation track remains open)
