feat(v2.7.0): add provenance, confidence, and reproducibility metadata

* add result provenance across major sections
* introduce confidence levels for ambiguous outputs
* distinguish observed facts from inferred summaries
* expand snapshot metadata for reproducibility
* improve error classification and partial snapshot handling
* include provenance and confidence in export
* add local notes for tracked domains and history
