Resolves #12795 Related: #12696

Adds an Active Hybrid GraphRAG subsection to the v13 Dream section, keeping it as supporting Dream/Brain evidence rather than the release headline. The section now explains the active frontier mechanics, ties the Agent OS back to Neo data/state/class primitives, adds a Mermaid mechanism diagram, and quotes the current generated Golden Path snapshot from resources/content/sandman_handoff.md with a proof-not-prophecy caveat.

Evidence: L1 (static source/doc audit + release-note diff) -> L1 required (documentation-only close target). No residuals.

Deltas from ticket

• Used the raw Golden Path snapshot as a quote, with an explicit caveat that it is generated, inspectable, and challengeable rather than hand-polished release prose.
• Preserved the existing Dream loop diagram and placed the new Active Hybrid GraphRAG mechanism after the Golden Path boundary guardrail to avoid a diagram dump.

Test Evidence

• git diff --check
• git diff --cached --check before commit
• Pre-commit hook passed, including node ./buildScripts/util/check-whitespace.mjs
• git log origin/dev..HEAD --format=... showed only 49344be01 docs(release): amplify active Hybrid GraphRAG (#12795) and no stray close keywords.
• Branch freshness passed: merge-base HEAD origin/dev == origin/dev.

Post-Merge Validation

• v13 release-note page renders the new Mermaid diagram and Golden Path quote cleanly in the docs/portal surface.
