enricobuehlerandClaude Fable 5 9bf72cdfb5 fix(host): forward reconfigure_bitrate through TrackedEncoder + probe --rebitrate validator
The gpu-session TrackedEncoder wrapper delegates every Encoder method by
hand, so the new reconfigure_bitrate fell through to the trait's false
default and EVERY bitrate change silently took the rebuild+IDR path — the
live .21 A/B caught it (host log said 'rebuilt', never 'in place').

Also:
- punktfunk-probe --rebitrate KBPS:SECS — headless mid-stream SetBitrate
  validator (cursor-wiggles so a damage-driven idle desktop keeps
  publishing frames through the switch). Live-verified on .21: one NVENC
  session open, then 'encoder bitrate reconfigured in place (adaptive
  bitrate — no IDR)' at 20→60 Mbps.
- on-hardware nvenc_cuda reconfigure smoke test (20→60→10 Mbps in place,
  zero IDRs — green on the RTX 5070 Ti).
- BitrateChanged doc no longer claims the switch costs an IDR.
