docs: decode recurring blocked-goal signature

[rysweet]

Summary

• Decodes the recurring kgpacks-rs blocked-goal cognitive-memory signature into the affected workstreams and marker counts.
• Classifies the recurrence as stale orchestration/state reconciliation drift rather than a current implementation, dependency, or validation block.
• Documents concrete next actions: reconcile local goal-board state, handle stale PR Implement the next Simard product block after local engineer loop #45 hygiene, add upstream-closed preflight suppression, collapse repeated memory keys, and keep gym skips as downstream symptoms unless current gym evidence exists.

Validation

• python3 -m mkdocs build --strict --quiet
• pre-commit commit-stage gates, including cargo fmt and cargo clippy --release --no-deps -- -D warnings
