feat: Add task dependency management and enhance task information display

- Implemented  and  commands:
    - Added validation to prevent circular and duplicate dependencies.
    - Ensured proper error handling for invalid task IDs.
    - Updated task files (tasks.json and individual task files) after changes.
- Enhanced the  command to provide a detailed view of tasks:
    - Displayed dependencies with status (using color-coded output).
    - Included comprehensive task information (description, details, etc.).
- Updated documentation: README, scripts/README.md, and dev_workflow.mdc.
- Prepared package for publishing (version bump).

+## Finding the Next Task
+
+The `next` command helps you determine which task to work on next based on dependencies and status:
+
+```bash
+# Show the next task to work on
+node scripts/dev.js next
+
+# Specify a different tasks file
+node scripts/dev.js next --file=custom-tasks.json
+```
+
+This command:
+
+1. Identifies all **eligible tasks** - pending or in-progress tasks whose dependencies are all satisfied (marked as done)
+2. **Prioritizes** these eligible tasks by:
+   - Priority level (high > medium > low)
+   - Number of dependencies (fewer dependencies first)
+   - Task ID (lower ID first)
+3. **Displays** comprehensive information about the selected task:
+   - Basic task details (ID, title, priority, dependencies)
+   - Detailed description and implementation details
+   - Subtasks if they exist
+4. Provides **contextual suggested actions**:
+   - Command to mark the task as in-progress
+   - Command to mark the task as done when completed
+   - Commands for working with subtasks (update status or expand)
+
+This feature ensures you're always working on the most appropriate task based on your project's current state and dependency structure.
+
+## Showing Task Details
+
+The `show` command allows you to view detailed information about a specific task:
+
+```bash
+# Show details for a specific task
+node scripts/dev.js show 1
+
+# Alternative syntax with --id option
+node scripts/dev.js show --id=1
+
+# Show details for a subtask
+node scripts/dev.js show --id=1.2
+
+# Specify a different tasks file
+node scripts/dev.js show 3 --file=custom-tasks.json
+```
+
+This command:
+
+1. **Displays comprehensive information** about the specified task:
+   - Basic task details (ID, title, priority, dependencies, status)
+   - Full description and implementation details
+   - Test strategy information
+   - Subtasks if they exist
+2. **Handles both regular tasks and subtasks**:
+   - For regular tasks, shows all subtasks and their status
+   - For subtasks, shows the parent task relationship
+3. **Provides contextual suggested actions**:
+   - Commands to update the task status
+   - Commands for working with subtasks
+   - For subtasks, provides a link to view the parent task
+
+This command is particularly useful when you need to examine a specific task in detail before implementing it or when you want to check the status and details of a particular task.
+
+## Managing Task Dependencies
+
+The `add-dependency` and `remove-dependency` commands allow you to manage task dependencies:
+
+```bash
+# Add a dependency to a task
+node scripts/dev.js add-dependency --id=<id> --depends-on=<id>
+
+# Remove a dependency from a task
+node scripts/dev.js remove-dependency --id=<id> --depends-on=<id>
+```
+
+These commands:
+
+1. **Allow precise dependency management**:
+   - Add dependencies between tasks with automatic validation
+   - Remove dependencies when they're no longer needed
+   - Update task files automatically after changes
+
+2. **Include validation checks**:
+   - Prevent circular dependencies (a task depending on itself)
+   - Prevent duplicate dependencies
+   - Verify that both tasks exist before adding/removing dependencies
+   - Check if dependencies exist before attempting to remove them
+
+3. **Provide clear feedback**:
+   - Success messages confirm when dependencies are added/removed
+   - Error messages explain why operations failed (if applicable)
+
+4. **Automatically update task files**:
+   - Regenerates task files to reflect dependency changes
+   - Ensures tasks and their files stay synchronized
