Subject: [PATCH] feat(pdftract-68pe): add Dockerfile with FEATURES build-arg
 support

Adds multi-stage Dockerfile supporting three feature variants:
- default: baseline features, distroless base (~20 MB)
- ocr: default + OCR (Tesseract), debian-slim base (~120 MB)
- full: all features, debian-slim base (~140 MB)

The FEATURES build-arg selects the variant at build time.
