chore(openspec): drop 9 superseded proposals + 11 stub archive files

Drop 9 batch proposals that are superseded by the boocode-lift-analysis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.

+
+## Three Integration Points
+
+### 1. Atlas Prompt Instruction (immediate, zero-code)
+
+Add to the Atlas orchestration prompt:
+
+```
+## Paseo Bridge Protocol
+When you call task() and receive a child session ID:
+  - On task creation: `paseo import <session-id> --provider opencode --label omo=true --label type=<category>`
+  - On task completion: Track the session ID; clean up later
+```
+
+**Pros:** Zero code changes, works immediately
+**Cons:** Ephemeral (per-session context), must be repeated every session
+
+### 2. OpenCode Skill (durable, scripted)
+
+Create a reusable skill at `.opencode/skills/omo-paseo-bridge/SKILL.md` that:
+
+- Accepts a child session ID and task type
+- Calls `paseo import` with proper labels
+- Returns the imported agent ID
+- Handles errors (daemon not running, already imported)
+
+The Atlas prompt calls this skill instead of shelling out directly.
+
+### 3. PreToolUse Hook (fully automatic)
+
+A hook that intercepts `task()` calls before/after execution:
+
+- On `task()` launch: capture the session ID from the response
+- On `task()` completion: `paseo archive` the corresponding agent
+
+**Pros:** Fully automatic, no prompt changes needed
+**Cons:** Hook system support varies by runtime
+
+## Data Model
+
+```typescript
+// Labels applied to each imported Paseo agent
+{
+  "omo": "true",
+  "omo.type": "explore | quick | ultrabrain | deep | visual-engineering | unspecified-low | unspecified-high | writing", 
+  "omo.parent_session": "ses_xxx",    // The session that called task()
+  "omo.description": "Search codebase for X"  // The task prompt description
+}
+```
+
+## CLI Bridge Script (Optional)
+
+A small `omo-paseo` CLI that wraps common operations:
+
+```bash
+# Import all unregistered child sessions
+omo-paseo sync
+
+# Clean up completed/failed OMO agents
+omo-paseo prune
+
+# Show OMO agents in paseo format
+omo-paseo ls
+```
