pi-chrome 0.11.5: plain-English audit pass for /chrome-doctor, /chrome-background, /chrome-onboard, README

Replaces remaining jargon in every user-facing string:

- /chrome-doctor: 'Local bridge: mode=server, url=...' -> 'This pi
  session is running the Chrome connection for this machine.'
  'EXTENSION VERSION MISMATCH ...' -> 'The Chrome companion extension
  is on an old version (X); this pi-chrome is Y.'
  'chrome_evaluate("1+1") = 2' -> 'pi-chrome can run code in the
  active Chrome tab.'
  'navigator.webdriver=true on current tab — site fingerprinting may
  flag automation.' -> 'Your Chrome is reporting itself as automated
  to websites. Some sites use this signal to block sign-ins or bot
  checks.'
- /chrome-background description + notify: drops 'silent/background
  mode', frames as 'quiet mode' vs 'watch mode'.
- /chrome-onboard: walks through the click-by-click steps instead of
  saying 'Developer mode -> Load unpacked'.
- session_start notify: drops 'Chrome profile bridge'; says 'pi-chrome
  connected' / 'waiting for the Chrome companion to connect'.
- README 'Trusted-input mode (CDP)' section rewritten as 'Click modes'
  with plain prose explaining quiet vs real-looking clicks and when
  each fails.

Tool descriptions (seen by the agent) keep precise terminology.
