What shipps in 4.1.0

Dempster-Shafer, for real: replaced the noisy-OR (which was silently identical to CF) with genuine Dempster's rule of combination on the {H, ¬H} frame — conflict-K renormalization, disconfirming evidence, plausibility that actually drops below 1.0.
18-rule MYCIN base with three disconfirming rules; fixed a DS crash on numeric beliefs; hardened the driver for parallel-tool models and fixed an invalid default model id.
A captured live transcript (docs/sample-session-ds-conflict.md) proving it end-to-end, with numbers matching the engine and Claude narrating the CF-vs-DS distinction.
All findings from a high-effort code review verified (one refuted as a false positive) and fixed.
