Add Dockerfile and Docker Compose for containerized deployment

[Copilot]

Adds container support to enable consistent development and deployment environments.

Changes

• Dockerfile — python:3.12-slim base; upgrades pip, installs deps, sets PYTHONPATH=/app/include for local packages (ez, sandbox, utilities), exposes port 8000, and launches via python -m core.startup --host 0.0.0.0 --port 8000
• requirements.txt — pinned minimum versions for all third-party runtime deps: starlette, uvicorn[standard], pydantic>=2.0, sqlalchemy>=2.0, pyyaml, python-seamless, watchfiles
• .dockerignore — excludes .venv, __pycache__, .git, lib/, bin/, and build artefacts
• docker-compose.yml — defines a web service that builds from the local Dockerfile, maps port 8000, mounts the project root as a volume for live code changes, and sets PYTHONPATH

Usage

docker build -t ez-web .
docker run -p 8000:8000 ez-web

Or with Docker Compose:

docker compose up

To serve a specific site directory, mount it and pass the path:

docker run -p 8000:8000 -v /path/to/site:/site ez-web \
  python -m core.startup /site --host 0.0.0.0 --port 8000

@copilot how about a compose file?

Added in commit 7991fb2. You can now start the app with:

docker compose up
