refactor(javascript)!: share semantic evidence at fact construction

Intern shared provenance in a graph-scoped context registry while retaining exact locations on every fact. Semantic traces carry their referenced context subset, and portable graph validation rejects stale or dangling commitments.

BREAKING CHANGE: Semantic graph facts now store evidence context IDs and locations. Graph and semantic trace results require an inline evidence_contexts table.
