feat: normalize durable fact extraction (#1012)

Closes #1012

- add structured session fact extraction with provenance, temporal metadata,
  canonical normalization, and contradiction grouping
- persist structured metadata into holographic memory auto-extraction with
  canonical-key dedupe across repeated ingests
- add fixture-backed transcript tests plus extraction quality evaluation
