Multi-monitor jumps, screen OCR, and generated sprite art

petctl gains screen verbs: `jump` (1-based number, name, next/prev/
primary/other, or a direction resolved from real geometry), `monitors`,
and `read` for OCR of a monitor's contents.

- monitors.py: pure layout model + jump-target resolution. The monitor
  list is published by PetWindow from QGuiApplication.screens() over a
  queued signal, so the controller and window agree on what "monitor 2"
  means; xrandr and Qt order screens differently on the same machine.
- screen_text.py: pull-only OCR (mss capture + Tesseract/RapidOCR).
  Nothing captures unless the server asks, and the text rides back up
  the tool-result relay so Bolt can read a screen mid-turn. Both deps
  optional, soft-failing with a reason. SCREEN_TEXT=false removes it.
- Query verbs are answered in controller._handle_command rather than
  pet_actions.describe(), because their output is the point.
- scripts/generate_bolt_sprites.py draws every frame; walk/ is a
  side-view cycle stepped by distance travelled, not by the animation
  timer, so the planted paw tracks the window exactly. sprite.py loads
  it via EXTRA_ANIMATIONS keyed by name, with has() so callers can
  decline a placeholder blob.
