refactor: enhance add-task fuzzy search and fix duplicate banner display

- **Remove hardcoded category system** in add-task that always matched 'Task management'
- **Eliminate arbitrary limits** in fuzzy search results (5→25 high relevance, 3→10 medium relevance, 8→20 detailed tasks)
- **Improve semantic weighting** in Fuse.js search (details=3, description=2, title=1.5) for better relevance
- **Fix duplicate banner issue** by removing console.clear() and redundant displayBanner() calls from UI functions
- **Enhance context generation** to rely on semantic similarity rather than rigid pattern matching
- **Preserve terminal history** to address GitHub issue #553 about eating terminal lines
- **Remove displayBanner() calls** from: displayHelp, displayNextTask, displayTaskById, displayComplexityReport, set-task-status, clear-subtasks, dependency-manager functions

The add-task system now provides truly relevant task context based on semantic similarity rather than arbitrary categories and limits, while maintaining a cleaner terminal experience.

Changes span: add-task.js, ui.js, set-task-status.js, clear-subtasks.js, list-tasks.js, dependency-manager.js

Closes #553

-# Task ID: 97
-# Title: Create Taskmaster Jingle Implementation
-# Status: pending
-# Dependencies: 95, 57, 3, 2
-# Priority: medium
-# Description: Develop a musical jingle system for Taskmaster that plays sound effects during key CLI interactions to enhance user experience.
-# Details:
-This task involves implementing a sound system that plays audio cues during Taskmaster CLI operations. Key implementation steps include:
-
-1. Audio System Integration:
-   - Research and select appropriate audio library compatible with Node.js CLI applications
-   - Implement cross-platform audio playback (Windows, macOS, Linux)
-   - Create sound configuration options in .taskmasterconfig
-
-2. Jingle Design:
-   - Define sound triggers for key events (task creation, completion, errors, etc.)
-   - Create or source appropriate sound files (WAV/MP3 format)
-   - Implement volume control and mute option in settings
-
-3. CLI Integration:
-   - Add sound playback to core CLI commands (init, create, update, delete)
-   - Implement optional sound effects toggle via command line flags
-   - Ensure audio playback doesn't interfere with CLI performance
-
-4. Documentation:
-   - Update user guide with sound configuration instructions
-   - Add troubleshooting section for audio playback issues
-
-# Test Strategy:
-1. Verify audio plays correctly during each supported CLI operation
-2. Test sound configuration options across different platforms
-3. Confirm volume control and mute functionality works as expected
-4. Validate that audio playback doesn't affect CLI performance
-5. Test edge cases (no audio hardware, invalid sound files, etc.)
-6. Ensure sound effects can be disabled via configuration and CLI flags
