Subject: column cursor: real left/right movement + follow the ref UNDER the
 cursor

- ColumnCursor mixin for both views: h/l/left/right, w/b word-hops, 0/$ line
  ends; block cursor cell + word-under-cursor highlight rendered on the cursor
  line (region-refresh so it stays cheap). vertical moves clamp the column.
- follow/xrefs now use the token under the cursor, so a line with multiple refs
  follows the one you're pointing at (proven: 'return sub_A(sub_B,..)' -> cursor
  on sub_B follows sub_B). decomp matches a decompiler ref by exact name; disasm
  resolves the symbol, falling back to the line's from-xref (address column /
  hex operands are excluded so the default position still follows the target).
- horizontal scroll follows the cursor in the pseudocode view.
- dropped the f/b paging aliases (b is now word-back).
- pilot suite 34/34.
