Follow-ups to #1803, #1805 and #1806

- Block Attribute Manager: the error band's dismiss button is the close
  icon, not a "×" glyph the web build may not have.
- Two signatures wrapped to the 100-column limit.
- MCP tool schema digest updated for the new `block_def_dialog` and
  `attman_dialog` actions.
- Measurement docs: MEASUREGEOM's Quick mode.

+### Quick — `MEASUREGEOM` → `Q`

+As the cursor moves, the nearest geometry along the working plane's X and Y axes is measured live: cyan measurement lines and a Horizontal/Vertical readout appear by the cursor. A click prints the current readout to the command line and measuring continues; Enter ends the command. Angles where the lines meet slanted geometry are not shown yet.
