deploy: Dockerfile + docker-compose Traefik per VPS pm.tielogic.xyz

Dockerfile (multi-arch, python 3.13-slim):
- uv copiato da ghcr.io/astral-sh/uv per install deps
- System deps: libgl1 libglib2.0-0 (cv2) + libgomp1 (numba)
- uv sync --frozen --no-dev da uv.lock
- ENV: IMAGES_DIR=/data/images, HOST=0.0.0.0, PORT=8080
- HEALTHCHECK su GET /images ogni 30s

docker-compose.yml:
- Service pm2d con image ${REGISTRY}/pm2d:${TAG}
- Volume ./images:/data/images (persistenza upload/UI)
- Network esterna 'traefik' (adattare se diverso)
- Labels Traefik:
  - Router HTTPS Host(pm.tielogic.xyz) entrypoint websecure TLS letsencrypt
  - Middleware bodysize 50MB (upload multipart)
  - Redirect HTTP->HTTPS automatico

main.py: HOST/PORT da env (default 127.0.0.1:8080 per dev locale).

README: sezione Deploy con build/push/run su VPS.

.dockerignore: esclude .venv, Test/, benchmarks/, md files.
