pi-chrome 0.11.1: chrome_tap (CDP touch), smoother trustedScroll, cdp auto-recover

- chrome_tap tool: real browser-trusted touchstart/touchend via
  Input.dispatchTouchEvent for sites that gate on TouchEvent (mobile-
  first PWAs, swipe carousels). Always uses CDP; banner appears.
- trustedScroll: per-step delta capped at ~80px, n=6..60 steps with a
  bell-shaped weight curve, 22-52ms sleep between events so IntersectionObserver and rAF samples get gradient updates (fixes
  intersection-visibility / smooth-scroll tests).
- cdp() wrapper auto-detects stale debugger sessions (tab nav,
  DevTools toggle, manual cancel) and re-attaches+retries once
  instead of throwing 'Debugger is not attached'. Fixes intermittent
  failures during automated test sweeps.
