chore(openspec): drop 9 superseded proposals + 11 stub archive files

Drop 9 batch proposals that are superseded by the boocode-lift-analysis
(boocontext-audit, conductor upgrades, self-healing/verify-gate skills):
add-3tier-memory, import-llm-evaluator, import-pregel-engine, plugin-platform,
conductor-evolution, code-intelligence-upgrade, dev-workflow, ui-overhaul,
agent-reliability.

Delete 11 stub archive files (49-66B each, 'Status: Shipped. Archived.' only)
that provide zero documentation value over the existing CHANGELOG.md + git tags.

+# Behavioral Guidelines Store — Spec
+
+## Guideline Entity
+
+```typescript
+interface GuidelineContent {
+  condition: string;     // When...
+  action: string | null; // Then...
+  description: string | null;
+}
+
+interface Guideline {
+  id: string;
+  creationUtc: string;
+  content: GuidelineContent;
+  enabled: boolean;
+  tags: string[];
+  labels: string[];
+  metadata: Record<string, unknown>;
+  criticality: "low" | "medium" | "high";
+  title: string | null;
+  priority: number;
+}
+```
+
+## GuidelineDocumentStore
+
+File-based JSON store at `.boo/guidelines/`. Versioned with migration support.
+
+Methods:
+- `createGuideline(condition, action?, description?, ...) → Guideline`
+- `listGuidelines(tags?, labels?) → Guideline[]`
+- `readGuideline(id) → Guideline`
+- `updateGuideline(id, params) → Guideline`
+- `deleteGuideline(id) → void`
+- `findGuideline(content: {condition, action?}) → Guideline`
+
+Version migration chain (port from Parlant v0.1.0 → v0.11.0):
+- v0.1.0 → v0.2.0: add enabled field
+- v0.2.0 → v0.3.0: remove guideline_set (migration script only)
+- v0.3.0 → v0.4.0: add optional action, description, metadata
+- v0.4.0 → v0.5.0: description as optional
+- v0.5.0 → v0.6.0: add criticality (default "medium")
+- v0.6.0 → v0.7.0: add composition_mode (optional)
+- v0.7.0 → v0.8.0: add track (default true)
+- v0.8.0 → v0.9.0: add labels (default empty)
+- v0.9.0 → v0.10.0: add priority (default 0)
+- v0.10.0 → v0.11.0: add title (default null)
+
+## Tag & Label Filtering
+
+- `listGuidelines({tags: ["tag1"]})` → guidelines with ANY of the specified tags
+- `listGuidelines({labels: ["label1"]})` → guidelines with ALL specified labels (subset match)
+- Combined: both filters apply (intersection)
+
+## Journey → Guideline Projection
+
+Port of Parlant's `JourneyGuidelineProjection.project_journey_to_guidelines()`:
+
+- DFS traversal of Journey nodes from root
+- Each (edge, node) pair → one Guideline
+- Edge condition becomes guideline condition
+- Node action becomes guideline action
+- Edge/node metadata merged into guideline metadata with journey_node key
+- follow_ups list populated with downstream guideline IDs
+- BFS queue avoids infinite loops via visited set
+
+## Journey Backtrack Detection
+
+```typescript
+interface BacktrackCheck {
+  journeyId: string;
+  currentNodeId: string;
+  previousNodeId: string;
+  isBacktrack: boolean;
+  recommendation: string | null;
+}
+```
+
+Scans the edge list for source→target relationships. If the agent's current step has an edge back to a previously visited node (and that node is not in a forward path from current), it's flagged as a backtrack regression.
