Implement complete MCP server for parsing Primavera P6 XER files and exposing schedule data through MCP tools. All 4 user stories complete. Tools implemented: - load_xer: Parse XER files into SQLite database - list_activities: Query activities with pagination and filtering - get_activity: Get activity details by ID - list_relationships: Query activity dependencies - get_predecessors/get_successors: Query activity relationships - get_project_summary: Project overview with counts - list_milestones: Query milestone activities - get_critical_path: Query driving path activities Features: - Tab-delimited XER format parsing with pluggable table handlers - In-memory SQLite database for fast queries - Pagination with 100-item default limit - Multi-project file support with project selection - ISO8601 date formatting - NO_FILE_LOADED error handling for all query tools Test coverage: 81 tests (contract, integration, unit)
