Initial commit: CMM Report Analyzer

FastAPI app that parses CMM inspection reports (PDF/Excel/CSV),
computes SPC metrics (Cp/Cpk/Pp/Ppk, control limits, Shapiro-Wilk),
generates interactive Plotly charts, and provides AI-powered quality
summaries via Azure OpenAI with graceful fallback.

Includes 21 passing tests covering parsers, SPC calculations, and
API endpoints.
