pin package to exact commit (stale pip cache served pre-KV-cache 0.1.x — prefill missing); print installed version at boot

verification fixes: gradio-6 content-block normalization (multi-turn transcript corruption), boot-safe load_model (no crash-loop on hub hiccups), lock-free downloads + raceless device handling, per-boot log files (no day-file clobber), disconnect-aware logging w/ completed flag, surrogate-safe writes, sha256 session tags, empty-input guards

gradio 6: Chatbot type kwarg removed (messages is the native format); full Blocks graph verified headless against 6.23.1

0.2: KV-cached streaming decode w/ A/B toggle + bytes/s readout; public history logging via CommitScheduler w/ prominent disclosure (disabled gracefully without token)
