pi-chrome: humanize synthetic input + anti-automation test suite

Bump 0.8.0 → 0.9.1.

Companion extension (service_worker.js):
- humanise pointer paths: easing Bezier-ish interpolation w/ wobble, 12–42
  steps, 4–18 ms gaps; pointer position persisted across calls
- click point picked inside element rect, not dead center
- pointer events fill movementX/Y, screenX/Y, pressure (0.5 on down),
  pointerId, width/height, tilt, composed
- click sequence: humanMoveTo → pointerdown → focus → 45–140 ms hold →
  pointerup → mouseup → click
- per-character typing: keydown → keypress → beforeinput → value mutate
  (or execCommand for contenteditable) → input → keyup, with 25–95 ms
  hold + 35–140 ms inter-key; auto Shift chord for uppercase/symbols
- pressKeyInPage emits same cadence + handles printable insert / Backspace
- hoverPage: humanised path + 80–220 ms dwell
- dragPage: full HTML5 sequence (dragstart/drag/dragenter/dragover/
  dragleave/drop/dragend) with shared DataTransfer + pointer continuity
- new scrollPage: wheel events with front-loaded momentum-shaped deltas
- self-reload on version drift: SW reads x-pi-chrome-version header,
  reloads when older than pi-chrome

Pi side (index.ts):
- new chrome_scroll tool
- PI_CHROME_VERSION read from package.json (and re-read on every /next
  so future bumps take effect without pi restart)
- /chrome-doctor escalates version mismatch to top-line ✗ error and
  skips downstream capability probes when stale
- /next response carries x-pi-chrome-version header for SW self-heal

Test suite (test-suite/):
- 28 challenge pages each catching a different synthetic-event tell:
  isTrusted, webdriver/fingerprint, mouse entropy/timing/coords,
  pointer pressure/continuity, per-char cadence + framework invariants,
  user activation, honeypots, focus order, wheel scroll, drag+
  DataTransfer, contenteditable+Selection, paste/clipboard, native
  select, hover dwell, React valueTracker, keyboard modifiers, touch
  events, stack-trace fingerprint, viewport-edge clicks, mousemove
  rate, scroll momentum, IntersectionObserver visibility
- shared _lib.js exposes window.__verdict + writes localStorage so
  index.html dashboard aggregates results
- notes/bypass-ideas.md documents fixes still needed per challenge
