Merge branch 'main' into fix/876

- Implement Bitcoin/Ordinals inscription verification
- Add agent/ordinals_verification.py with blockchain verification
- Add docs/ordinals-verification.md with documentation

Addresses issue #876: [FRONTIER] Integrate Bitcoin/Ordinals Inscription Verification

Features:
1. Bitcoin RPC client for blockchain verification
2. Ordinals API client for inscription retrieval
3. Inscription verifier for content hash verification
4. Identity storage with verification proofs

Verification process:
1. Agent requests verification with inscription ID
2. System retrieves inscription from Ordinals API
3. Content hash verification against blockchain
4. Identity stored with verification proof

Components:
- BitcoinRPCClient: Blockchain communication
- OrdinalsAPI: Inscription retrieval
- InscriptionVerifier: Identity verification
- OrdinalsInscriptionSystem: Main verification system

+**Issue:** #876 - [FRONTIER] Integrate Bitcoin/Ordinals Inscription Verification
+
+## Overview
+
+This system verifies agent identity by checking SOUL.md inscriptions on the Bitcoin blockchain.
+
+## Architecture
+
+```

+|  +-------------+  +-------------+  +-------------+
++---------------------------------------------------+
+```
+
+## Components
+
+### 1. Bitcoin RPC Client (`BitcoinRPCClient`)
+Client for Bitcoin RPC communication.
+
+**Features:**
+- Blockchain info retrieval
+- Block verification
+- Transaction validation
+
+**Usage:**
+```python
+client = BitcoinRPCClient()
+info = await client.call("getblockchaininfo")
+block = await client.call("getblock", ["block_hash"])
+```
+
+### 2. Ordinals API Client (`OrdinalsAPI`)
+Client for Ordinals API communication.
+
+**Features:**
+- Inscription retrieval
+- Content verification
+- Hash validation
+
+**Usage:**
+```python
+api = OrdinalsAPI()
+inscription = await api.get_inscription("inscription_id")
+content = await api.get_inscription_content("inscription_id")
+```
+
+### 3. Inscription Verifier (`InscriptionVerifier`)
+Verifies agent identity against blockchain inscription.
+
+**Features:**
+- Content hash verification
+- Inscription validation
+- Identity storage
+
+**Usage:**
+```python
+verifier = InscriptionVerifier()
+identity = await verifier.verify_agent_identity("agent_id", "inscription_id")
+is_verified = verifier.is_agent_verified("agent_id")
+```
+
+### 4. Ordinals Inscription System (`OrdinalsInscriptionSystem`)
+Main system for Bitcoin/Ordinals inscription verification.
+
+**Features:**
+- Agent verification
+- Verification status checking
+- Reporting
+
+**Usage:**
+```python
+system = OrdinalsInscriptionSystem()
+result = await system.verify_agent("agent_id", "inscription_id")
+is_verified = system.is_agent_verified("agent_id")
+report = system.get_verification_report()
+```
+
+## Verification Process
+
+### 1. Agent Requests Verification
+```python
+# Agent provides inscription ID
+inscription_id = "abc123..."
+agent_id = "agent_001"
+```
+
+### 2. System Retrieves Inscription
+```python
+# Get inscription from Ordinals API
+inscription = await ordinals_api.get_inscription(inscription_id)
+```
+
+### 3. Content Verification
+```python
+# Get inscription content
+content = await ordinals_api.get_inscription_content(inscription_id)
+
+# Calculate content hash
+content_hash = hashlib.sha256(content.encode()).hexdigest()
+
+# Verify hash matches inscription
+if content_hash != inscription.content_hash:
+    # Verification failed
+    return INVALID
+```
+
+### 4. Identity Storage
+```python
+# Store verified identity
+identity = AgentIdentity(
+    agent_id=agent_id,
+    inscription=inscription,
+    soul_hash=content_hash,
+    verified_at=time.time(),
+    status=VERIFIED
+)
+```
+
+## Usage Examples
+
+### Verify Agent
+```python
+# Create system
+system = OrdinalsInscriptionSystem()
+
+# Verify agent
+result = await system.verify_agent("agent_001", "inscription_123")
+print(f"Status: {result['status']}")
+```
+
+### Check Verification Status
+```python
+# Check if agent is verified
+is_verified = system.is_agent_verified("agent_001")
+print(f"Agent verified: {is_verified}")
+```
+
+### Get Verification Report
+```python
+# Get report for all agents
+report = system.get_verification_report()
+print(f"Verified: {report['verified']}")
+print(f"Unverified: {report['unverified']}")
+```
+
+## Integration with Hermes
+
+### Loading Verification System
+```python
+# In agent/__init__.py
+from agent.ordinals_verification import OrdinalsInscriptionSystem
+
+# Create verification system
+verification = OrdinalsInscriptionSystem()
+
+# Verify agent before mission
+is_verified = verification.is_agent_verified(agent_id)
+if not is_verified:
+    # Request verification
+    result = await verification.verify_agent(agent_id, inscription_id)
+```
+
+### Exposing via MCP
+```python
+# In agent/mcp_server.py
+from agent.ordinals_verification import OrdinalsInscriptionSystem
+
+# Register verification tools
+server.register_tool(
+    "verify_agent",
+    "Verify agent against blockchain inscription",
+    lambda args: verification.verify_agent(**args),
+    {...}
+)
+
+server.register_tool(
+    "check_verification",
+    "Check agent verification status",
+    lambda args: verification.is_agent_verified(**args),
+    {...}
+)
+```
+
+## Testing
+
+### Unit Tests
+```bash
+python -m pytest tests/test_ordinals_verification.py -v
+```
+
+### Integration Tests
+```bash
+# Create verification system
+system = OrdinalsInscriptionSystem()
+
+# Verify agent
+result = await system.verify_agent("test_agent", "test_inscription")
+
+# Check verification
+is_verified = system.is_agent_verified("test_agent")
+assert is_verified
+```

+## Conclusion
+
+This system provides blockchain-based identity verification for agents:
+1. **Verification** against Bitcoin/Ordinals inscriptions
+2. **Identity storage** with verification proofs
+3. **Status checking** for agent verification
+4. **Reporting** for verification rates
