T007: Contract tests for index_repository MCP tool.
These tests validate the MCP protocol contract for repository indexing functionality.
Tests MUST fail initially as the tool is not yet implemented (TDD approach).
Performance Requirements:
- Target: 10K files in < 60 seconds
- Maximum: 10K files in < 120 seconds
