d61a8aff8b refactor: Remove unused code and fix nil dereference issues 
- Remove unused exported functions from pkg/database (session tracking,
  bulk hashrate inserts, various query helpers)
- Remove unused exported functions from pkg/node (identity management,
  bundle operations, controller methods)
- Make internal-only functions unexported in config_manager.go and database.go
- Remove unused EventProfile* constants from events.go
- Add GetCommit() and GetBuildDate() to expose version.go variables
- Fix potential nil dereference issues flagged by Qodana:
  - Add nil checks for GetIdentity() in controller.go, transport.go, worker.go
  - Add nil checks for GetPeer() in peer_test.go
  - Add nil checks in worker_test.go

b24a3f00d6 fix: Add timeouts, atomic writes, and thread safety improvements 
- Add 30s context timeout for database transactions in hashrate.go
- Add helper function for parsing SQLite timestamps with error logging
- Implement atomic file writes (temp + rename) for profile_manager.go,
  config_manager.go, and peer.go to prevent corruption on crash
- Add 5s timeout for stats collection per miner in manager.go
- Add 5s timeout for stdin writes in miner.go
- Clean up config file on failed miner start in xmrig_start.go
- Implement debounced saves (5s) for peer registry to reduce disk I/O
- Fix CheckInstallation data race in xmrig.go and ttminer.go by adding
  proper mutex protection around shared field updates
- Add 10s handshake timeout for WebSocket connections in transport.go
- Update peer_test.go to call Close() before reload to flush changes

006dd3712e fix: Address critical security and concurrency issues 
Security fixes:
- Remove hardcoded wallet address from CLI defaults (start.go, serve.go)
  Pool and wallet are now required flags or must be provided explicitly
- Change file permissions from 0644 to 0600 for sensitive config files
  Affects: xmrig config, profiles, settings, config cache
- Fix path traversal in untar() - now returns error instead of silently skipping

Concurrency fix:
- Fix race condition in GetStats() - was using RLock while writing m.FullStats
  Changed to Lock/Unlock in both xmrig_stats.go and ttminer_stats.go
