Subject: mouse: click to place cursor, double-click to follow

- ColumnCursor.on_click maps the click to a virtual (line, column) via
  event.get_content_offset (handles padding/border) + scroll_offset, then places
  the line+column cursor (disasm posts CursorMoved for the status line).
- double-click (event.chain>=2) = place cursor + follow the symbol under it,
  identical to selecting it and pressing Enter.
- works in both views (verified: disasm click on 'call sub_XXXX' lands on the
  exact token; pseudocode click maps columns with no padding).
- pilot suite 36/36.
