pi-chrome 0.14.2: recover from foreign-extension input overlays

When a different Chrome extension (password manager, autofill popup,
etc.) anchors an overlay to the focused input, Chrome's CDP refuses
our Input.dispatchMouseEvent with 'Cannot access a chrome-extension://
URL of different extension'. The CDP target list shows the foreign
chrome-extension:// URL as type:'other' attached to the same tab.

New behaviour in cdp() wrapper:
1. On that specific error for any Input.* call, snapshot CDP targets
   to identify the offending extension id and log it (foreign-ext-
   detected event added to ring buffer).
2. Send Esc via Input.dispatchKeyEvent (key dispatch routes by focus,
   not coordinates, so it bypasses the overlay) to dismiss the popup.
3. Retry the original Input.* call once.
4. If retry still fails, throw a clear error naming the foreign
   extension id and listing three concrete workarounds: disable that
   extension on the page, use Tab-to-focus instead of clicking, or
   run /chrome quiet off.
