Two new specialist agents for /gsd-ingest-docs (#2387):
- gsd-doc-classifier: reads one doc, writes JSON classification
({ADR|PRD|SPEC|DOC|UNKNOWN} + title + scope + cross-refs + locked).
Heuristic-first, LLM on ambiguous. Designed for parallel fan-out per doc.
- gsd-doc-synthesizer: consumes all classifications + sources, applies
precedence rules (ADR>SPEC>PRD>DOC, manifest-overridable), runs cycle
detection on cross-ref graph, enforces LOCKED-vs-LOCKED hard-blocks
in both modes, writes INGEST-CONFLICTS.md with three buckets
(auto-resolved, competing-variants, unresolved-blockers) and
per-type intel staging files for gsd-roadmapper.
Also updates docs/ARCHITECTURE.md total-agents count (31 → 33) and the
copilot-install expected agent list.
