enricobuehlerandClaude Fable 5 ba89b9fcd0 feat(tools): display-disturb learns the bench moves the field sessions needed
Three upgrades from the on-glass rounds on .173/.221:

- `ddc-open` timing: the handle-ACQUISITION cost per monitor is reported even
  when it yields no physical handles — the poller's first contact with a
  virtual display, exactly what the DDC-fail-fast driver work changes; the
  old code silently skipped handle-less monitors, which on a streaming host
  in exclusive topology is every monitor there is.
- Monitors are labeled by GDI device name (\\.\DISPLAYn) so a virtual
  display and a panel are tellable apart in the correlation log.
- `extend` mode: one SDC_TOPOLOGY_EXTEND poke — re-activates every
  attachable display, i.e. the exact 'non-managed display re-activated'
  event the exclusive watchdog evicts. One shot, not a loop: trigger a
  reassert round, observe the recovery.
