chore: enhance .gitignore and remove obsolete documentation files

- Reorganize .gitignore with categorized sections for better maintainability
- Add comprehensive ignore patterns for Python, Node.js, databases, logs, and build artifacts
- Add project-specific ignore rules for coordinator, explorer, and deployment files
- Remove outdated documentation: BITCOIN-WALLET-SETUP.md, LOCAL_ASSETS_SUMMARY.md, README-CONTAINER-DEPLOYMENT.md, README-DOMAIN-DEPLOYMENT.md

+# Blockchain Operations Skill
+
+This skill provides standardized procedures for managing AITBC blockchain nodes, verifying transactions, and optimizing mining operations.
+
+## Overview
+
+The blockchain operations skill ensures reliable management of all blockchain-related components including node synchronization, transaction processing, mining operations, and network health monitoring.
+
+## Capabilities
+
+### Node Management
+- Node deployment and configuration
+- Sync status monitoring
+- Peer management
+- Network diagnostics
+
+### Transaction Operations
+- Transaction verification and debugging
+- Gas optimization
+- Batch processing
+- Mempool management
+
+### Mining Operations
+- Mining performance optimization
+- Pool management
+- Reward tracking
+- Hash rate optimization
+
+### Network Health
+- Network connectivity checks
+- Block propagation monitoring
+- Fork detection and resolution
+- Consensus validation
+
+## Common Workflows
+
+### 1. Node Health Check
+- Verify node synchronization
+- Check peer connections
+- Validate consensus rules
+- Monitor resource usage
+
+### 2. Transaction Debugging
+- Trace transaction lifecycle
+- Verify gas usage
+- Check receipt status
+- Debug failed transactions
+
+### 3. Mining Optimization
+- Analyze mining performance
+- Optimize GPU settings
+- Configure mining pools
+- Monitor profitability
+
+### 4. Network Diagnostics
+- Test connectivity to peers
+- Analyze block propagation
+- Detect network partitions
+- Validate consensus state
+
+## Supporting Files
+
+- `node-health.sh` - Comprehensive node health monitoring
+- `tx-tracer.py` - Transaction tracing and debugging tool
+- `mining-optimize.sh` - GPU mining optimization script
+- `network-diag.py` - Network diagnostics and analysis
+- `sync-monitor.py` - Real-time sync status monitor
+
+## Usage
+
+This skill is automatically invoked when you request blockchain-related operations such as:
+- "check node status"
+- "debug transaction"
+- "optimize mining"
+- "network diagnostics"
+
+## Safety Features
+
+- Automatic backup of node data before operations
+- Validation of all transactions before processing
+- Safe mining parameter adjustments
+- Rollback capability for configuration changes
+
+## Prerequisites
+
+- AITBC node installed and configured
+- GPU drivers installed (for mining operations)
+- Proper network connectivity
+- Sufficient disk space for blockchain data
