TET-1267 MCP: python-sdk integration

[seer-by-sentry]

Bug: The code imports MCPIntegration from sentry_sdk.integrations.mcp, but this class and module do not exist, causing an import error on startup.
_{(Severity: Critical 0.90 | Confidence: 0.98)}

🔍 Detailed Analysis

The code attempts to import MCPIntegration from sentry_sdk.integrations.mcp in test-mcp/main_lowlevel.py, test-mcp/main_fastmcp.py, and test-mcp/main.py. However, neither the MCPIntegration class nor the sentry_sdk.integrations.mcp module exists in the accessible codebase. Executing any of these scripts will raise an ImportError or ModuleNotFoundError, which will prevent the application from starting.

💡 Suggested Fix

Implement the MCPIntegration class within the sentry-python SDK. Alternatively, remove the test files that import this non-existent class until the implementation is available.
