feat(research): Adds MCP tool for command

- New MCP Tool: research tool enables AI-powered research with project context
- Context Integration: Supports task IDs, file paths, custom context, and project tree
- Fuzzy Task Discovery: Automatically finds relevant tasks using semantic search
- Token Management: Detailed token counting and breakdown by context type
- Multiple Detail Levels: Support for low, medium, and high detail research responses
- Telemetry Integration: Full cost tracking and usage analytics
- Direct Function: researchDirect with comprehensive parameter validation
- Silent Mode: Prevents console output interference with MCP JSON responses
- Error Handling: Robust error handling with proper MCP response formatting

This completes subtasks 94.5 (Direct Function) and 94.6 (MCP Tool) for the research command implementation, providing a powerful research interface for integrated development environments like Cursor.

Updated documentation across taskmaster.mdc, README.md, command-reference.md, examples.md, tutorial.md, and docs/README.md to highlight research capabilities and usage patterns.

+### Research-Driven Development
+
+Task Master includes a powerful research tool that provides fresh, up-to-date information beyond the AI's knowledge cutoff. This is particularly valuable for:
+
+#### Getting Current Best Practices
+
+```
+Before implementing task 5 (authentication), research the latest JWT security recommendations.
+```
+
+The agent will execute:
+
+```bash
+task-master research "Latest JWT security recommendations 2024" --id=5
+```
+
+#### Research with Project Context
+
+```
+Research React Query v5 migration strategies for our current API implementation.
+```
+
+The agent will execute:
+
+```bash
+task-master research "React Query v5 migration strategies" --files=src/api.js,src/hooks.js
+```
+
+#### Research and Update Pattern
+
+A powerful workflow is to research first, then update tasks with findings:
+
+```
+Research the latest Node.js performance optimization techniques and update task 12 with the findings.
+```
+
+The agent will:
+
+1. Run research: `task-master research "Node.js performance optimization 2024" --id=12`
+2. Update the task: `task-master update-subtask --id=12.2 --prompt="Updated with latest performance findings: [research results]"`
+
+#### When to Use Research
+
+- **Before implementing any new technology**
+- **When encountering security-related tasks**
+- **For performance optimization tasks**
+- **When debugging complex issues**
+- **Before making architectural decisions**
+- **When updating dependencies**
+
+The research tool automatically includes relevant project context and provides fresh information that can significantly improve implementation quality.
