Enhance job management functionality and improve execution handling

- Implemented comprehensive job management features, including pagination for job listing, active job retrieval, and job counting. - Enhanced job saving logic to support both creation and updates, ensuring proper handling of job metadata. - Introduced category management with automatic creation and retrieval of categories during job operations. - Added execution management capabilities, including progress tracking and logging for job executions. - Improved error handling and validation across job and execution methods, ensuring robustness in job processing. - Updated documentation to reflect new features and usage examples for job management and execution tracking.

-# Job
+# Job Framework
+
+A comprehensive task scheduling and execution framework supporting two execution modes: goroutine mode and process mode.
+
+## Features
+
+### 1. Database CRUD Operations
+
+- **Jobs Management**: Create, read, update, delete jobs
+- **Categories Management**: Automatic creation and management of job categories
+- **Executions Management**: Complete lifecycle management of job execution instances
+- **Logs Management**: Detailed execution logging and querying
+
+### 2. Worker Management System
+
+- **Goroutine Mode (GOROUTINE)**: Lightweight, fast execution
+- **Process Mode (PROCESS)**: Independent process, isolated execution
+- **Concurrency Control**: Support for multiple workers executing jobs concurrently
+- **Resource Management**: Automatic management of worker pools and resource allocation
+
+### 3. Progress Tracking
+
+- **Real-time Progress Updates**: Support for progress updates during job execution
+- **Database Persistence**: Progress information automatically saved to database
+- **Callback Support**: Support for progress update callback functions
+
+### 4. Logging System
+
+- **Multi-level Logging**: Debug, Info, Warn, Error, Fatal, Panic, Trace
+- **Structured Logging**: Includes execution context, timestamps, sequence numbers, etc.
+- **Database Storage**: All logs automatically saved to database

+
+## Usage Examples
+
+### Creating and Executing One-time Jobs
+
+```go
+// Create a goroutine mode one-time job
+job, err := job.Once(job.GOROUTINE, map[string]interface{}{
+    "name": "Example Job",
+    "description": "This is an example job",
+})
+
+// Add handler function
+handler := func(ctx context.Context, execution *job.Execution) error {
+    execution.Info("Job started")
+    execution.SetProgress(50, "In progress...")
+
+    // Execute business logic
+    time.Sleep(1 * time.Second)
+
+    execution.SetProgress(100, "Completed")
+    execution.Info("Job completed")
+    return nil
+}
+
+err = job.Add(1, handler)
+if err != nil {
+    return err
+}
+
+// Start the job
+err = job.Start()
+```
+
+### Creating Scheduled Jobs
+
+```go
+// Create a cron-based scheduled job
+cronJob, err := job.Cron(job.PROCESS, map[string]interface{}{
+    "name": "Cleanup Task",
+}, "0 2 * * *") // Execute daily at 2 AM
+
+err = cronJob.Add(1, cleanupHandler)
+err = cronJob.Start()
+```
+
+### Creating Daemon Jobs
+
+```go
+// Create a continuously running daemon job
+daemonJob, err := job.Daemon(job.GOROUTINE, map[string]interface{}{
+    "name": "Monitor Daemon",
+})
+
+daemonHandler := func(ctx context.Context, execution *job.Execution) error {
+    ticker := time.NewTicker(5 * time.Second)
+    defer ticker.Stop()
+
+    for {
+        select {
+        case <-ctx.Done():
+            return ctx.Err()
+        case <-ticker.C:
+            // Execute periodic tasks
+            execution.Info("Performing monitor check")
+        }
+    }
+}
+
+err = daemonJob.Add(1, daemonHandler)
+err = daemonJob.Start()
+```
+
+## Data Models
+
+### Job
+
+- Supports three scheduling types: one-time, scheduled, and daemon
+- Supports two execution modes: goroutine and process
+- Contains complete job metadata and configuration
+
+### Execution
+
+- Each job execution creates an execution instance

+
+### Category
+
+- Automatic creation and management of job categories
+- Supports hierarchical category structures
+
+### Log
+
+- Detailed execution log records
+- Supports multiple log levels
+- Contains execution context information

+
+## Architecture
+
+The framework follows a modular architecture with clear separation of concerns:
+
+- **Data Layer** (`data.go`): Handles all database operations
+- **Execution Layer** (`execution.go`, `job.go`): Manages job execution logic
+- **Worker Layer** (`worker.go`): Manages worker pools and job distribution
+- **Progress Layer** (`progress.go`): Handles progress tracking and updates
+- **Type Layer** (`types.go`): Defines all data structures and constants
+
+Each layer is thoroughly tested with comprehensive unit tests to ensure reliability and maintainability.
