Error Handling:
- Fix silent Write() error in WebSocket (events.go)
- Add error context to transport handshake messages
- Check os.MkdirAll error in zip extraction (miner.go)
- Explicitly ignore io.Copy errors on drain with comments
- Add retry logic (2 attempts) for transient stats collection failures
Resource Lifecycle:
- Add shutdown mechanism to DigestAuth goroutine
- Call Service.Stop() on context cancellation
- Add NodeService transport cleanup to Service.Stop()
- Fix WriteStdin goroutine leak on timeout with non-blocking send
API Design:
- Add profile validation (name, miner type required)
- Return 404 instead of 500 for missing profile PUT
- Make DELETE profile idempotent (return success if not found)
- Standardize error responses in node_service.go handlers
Observability:
- Add logging for P2P GetAllStats failures
- Add request ID correlation helper for handler logs
- Add logging for miner process exits (xmrig_start.go)
- Rate limit debug logs in transport hot path (1 in 100)
- Add metrics infrastructure with /metrics endpoint

Migrate all log.Printf/Println calls across the codebase to use the
new pkg/logging structured logging package. This provides consistent
log formatting with levels, timestamps, and structured key-value fields.
Files updated:
- pkg/mining/manager.go, service.go, events.go, miner.go
- pkg/mining/xmrig_start.go, ttminer_start.go
- pkg/mining/syslog_unix.go, syslog_windows.go
- pkg/database/hashrate.go
- pkg/node/worker.go, transport.go, peer.go

- Remove deprecated GetDB() function that exposed raw DB pointer
- Fix GetLatestHashrate to distinguish sql.ErrNoRows from real errors
- Document async saves in PeerRegistry mutation methods
- Fix deadlock in XMRig/TTMiner Start() by moving CheckInstallation
call before acquiring the main lock (Go RWMutex doesn't allow
recursive locking)

Networking/Protocol fixes:
- Add HTTP server timeouts (Read/Write/Idle/ReadHeader) in service.go
- Fix CORS address parsing to use net.SplitHostPort safely
- Add request body size limit middleware (1MB max)
- Enforce MaxConns limit in WebSocket upgrade handler
- Fix WebSocket origin validation to only allow localhost
- Add read/write deadlines to WebSocket connections
Memory leak fixes:
- Add sync.Once to Manager.Stop() to prevent double-close panic
- Fix controller pending map leak by closing response channel
- Add memory reallocation for hashrate history slices when oversized
- Fix LogBuffer to truncate long lines and force reallocation on trim
- Add process wait timeout to prevent goroutine leaks on zombie processes
- Drain HTTP response body on copy error to allow connection reuse
Segfault/panic prevention:
- Add nil check in GetTotalHashrate for stats pointer
- Fix hashrate history slice reallocation to prevent capacity bloat

Critical fixes:
- Release mutex before HTTP calls in GetStats() to prevent blocking
- Fix m.cmd race between Stop() and Wait() goroutine by capturing locally
- Add context support to GetStats() for proper request cancellation
High priority fixes:
- Add existence check in collectMinerStats() before operating on miners
- Add mutex-protected httpClient getter/setter for thread-safe test mocking
Changes:
- Miner interface now requires context.Context for GetStats()
- Stats HTTP requests timeout after 5 seconds (was 30s client default)
- All callers updated to pass context (service uses request context)

Security:
- Configure CORS to only allow local origins (localhost, 127.0.0.1, wails://)
- Add CLI args validation for TTMiner to block shell metacharacters
- Add HTTPPort validation (must be 1024-65535)
Reliability:
- Manager.Stop() now stops all running miners before shutdown
- Close stdin pipe on Start() error to prevent resource leak (xmrig, ttminer)
- Fix node_service query parameter parsing (was dead code)
Feature:
- Add TTMiner support in service layer (install, update check, info cache)
