pi-chrome 0.12.0: unify slash commands under /chrome

Replaces /chrome-doctor, /chrome-onboard, /chrome-background,
/chrome-trusted with a single /chrome command that takes subcommands:

  /chrome doctor                            (was /chrome-doctor)
  /chrome onboard                           (was /chrome-onboard)
  /chrome settings background [on|off]      (was /chrome-background)
  /chrome settings trusted [auto|off|on|status]   (was /chrome-trusted)

Running /chrome with no arguments opens a picker. Argument auto-
completion walks the tree (e.g. type '/chrome se<Tab>' to land on
'settings', then '/chrome settings t<Tab>' to land on 'trusted').

All user-visible references (notify messages, doctor output, agent
prompt primer, README) updated to the new paths.
