Create logger setup (internal/daemon/logger.go)\n\n```go\npackage daemon\n\nimport (\n    \"io\"\n    \"log/slog\"\n    \"os\"\n)\n\n// SetupLogger configures the daemon logger.\n// Returns a cleanup function to close the log file.\nfunc SetupLogger(logPath string, jsonFormat bool, level slog.Level) (func(), error) {\n    var w io.Writer = os.Stderr\n    var cleanup func()\n    \n    if logPath \\!= \"\" {\n        f, err := os.OpenFile(logPath, os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0600)\n        if err \\!= nil {\n            return nil, err\n        }\n        w = io.MultiWriter(os.Stderr, f)\n        cleanup = func() { f.Close() }\n    }\n    \n    var handler slog.Handler\n    opts := \u0026slog.HandlerOptions{Level: level}\n    \n    if jsonFormat {\n        handler = slog.NewJSONHandler(w, opts)\n    } else {\n        handler = slog.NewTextHandler(w, opts)\n    }\n    \n    slog.SetDefault(slog.New(handler))\n    \n    return cleanup, nil\n}\n```\n\n### 2. Add log level flag\n\nIn cmd/bd/daemon.go:\n```go\ndaemonCmd.Flags().String(\"log-level\", \"info\", \"Log level (debug, info, warn, error)\")\ndaemonCmd.Flags().Bool(\"log-json\", false, \"Output logs in JSON format\")\n```\n\n### 3. Replace fmt.Fprintf with slog calls\n\n**Pattern 1: Simple messages**\n```go\n// Before\nfmt.Fprintf(os.Stderr, \"Starting daemon on %s\\n\", socketPath)\n\n// After\nslog.Info(\"starting daemon\", \"socket\", socketPath)\n```\n\n**Pattern 2: Errors**\n```go\n// Before\nfmt.Fprintf(os.Stderr, \"Error: failed to connect: %v\\n\", err)\n\n// After\nslog.Error(\"failed to connect\", \"error\", err)\n```\n\n**Pattern 3: Debug info**\n```go\n// Before\nif debug {\n    fmt.Fprintf(os.Stderr, \"Received request: %s\\n\", method)\n}\n\n// After\nslog.Debug(\"received request\", \"method\", method)\n```\n\n**Pattern 4: Structured data**\n```go\n// Before\nfmt.Fprintf(logFile, \"Import: %d created, %d updated\\n\", created, updated)\n\n// After\nslog.Info(\"import completed\", \n    \"created\", created,\n    \"updated\", updated,\n    \"unchanged\", unchanged,\n    \"duration_ms\", duration.Milliseconds())\n```\n\n### 4. Files to Update\n\n| File | Changes |\n|------|---------|\n| cmd/bd/daemon.go | Add log flags, call SetupLogger |\n| internal/daemon/server.go | Replace fmt with slog |\n| internal/daemon/rpc_handler.go | Replace fmt with slog |\n| internal/daemon/sync.go | Replace fmt with slog |\n| internal/daemon/autoflush.go | Replace fmt with slog |\n| internal/daemon/logger.go | New file |\n\n### 5.
