Add comprehensive LLM tool detection support (18 tools)

Plan: Add More LLM Tool Detections

Based on the am-i-ai library (https://github.com/trieloff/am-i-ai), we need to add the following LLM tool detections:

• Review current implementation (5 tools: Claude, Cursor, Gemini, Copilot, generic_agent)
• Add new EnvironmentVariableValueRule for value-based detection
• Add Codex CLI detection (CODEX_CLI, CODEX_SANDBOX)
• Add Aider detection (OR_APP_NAME matching "Aider")
• Add Amp detection (AMP_HOME)
• Add Qwen Code detection (QWEN_CODE)
• Add Droid detection (DROID_CLI)
• Add OpenCode detection (OPENCODE_AI)
• Add Zed AI detection (ZED_ENVIRONMENT, ZED_TERM)
• Add Kimi CLI detection (KIMI_CLI)
• Add OpenHands detection (OR_APP_NAME matching "OpenHands")
• Add Goose detection (GOOSE_TERMINAL)
• Add Cline detection (CLINE_TASK_ID)
• Add Roo Code detection (ROO_CODE_TASK_ID)
• Add Windsurf detection (WINDSURF_SESSION)
• Add appropriate test cases for all new detections
• Add test cases for combinations of newer tools
• Run tests to validate changes (38/38 tests passing)
• Run formatting (no changes needed)
• Code review (addressed feedback)
• Security scan with CodeQL (no issues found)
• Update telemetry documentation

Summary

Successfully added detection support for 13 additional LLM tools, bringing the total from 5 to 18 supported tools. The implementation includes:

• New EnvironmentVariableValueRule for value-based matching
• Enhanced existing Claude and Cursor detections with additional environment variables
• Comprehensive test coverage (38 tests, all passing)
• Updated telemetry documentation
• No security vulnerabilities detected

<issue_title>Add more LLM tool detections</issue_title>
<issue_description>### Is your feature request related to a problem? Please describe.
There are libraries/ecosystems that have a more comprehensive set of detections for LLM tools, like https://github.com/trieloff/am-i-ai?tab=readme-ov-file#supported-ai-tools.

We should have parity in our detections, like adding Codex support in #52861</issue_description>

Pull request overview

Expands dotnet CLI telemetry’s LLM environment detection to cover a broader set of AI/agent tools (18 total), aiming for parity with the referenced “am-i-ai” detection list.

Changes:

• Added a new detection rule type to match specific environment variable values case-insensitively (EnvironmentVariableValueRule).
• Expanded LLMEnvironmentDetectorForTelemetry from a small set of tools to 18 tools, supporting multiple simultaneous detections (comma-separated).
• Extended unit test coverage to include the new tools and some multi-tool combinations.
