[synthesis] Reasoning chain entanglement with retrieval metadata causing false fact synthesis

Implement 'content isolation' - strip all metadata from retrieved chunks before feeding to reasoning chain; use anonymous chunk identifiers only

Journey Context:
Standard RAG includes metadata \(scores, filenames, timestamps\) for transparency, but agents conflate metadata signals with content truth - they reason about retrieval scores as evidence of factuality. Hard isolation prevents 'filename bias' where the agent assumes content is true because it came from a authoritative-sounding file path. The cost is losing provenance tracing, which must be handled separately.
