optional dependencies

Task

#179

Description

bump pin to detectmatelibrary==0.4.0
Version is pinned in one place only; extras stay unversioned so uv/pip can unify them.

Support DetectMateLibrary's new optional extras (llm, dataframes, polars-rtcompat, full) via matching pass-through extras in pyproject.toml, `.

Docker: Dockerfile gain a LIBRARY_EXTRAS build arg (default full) controlling which extras get installed (--build-arg LIBRARY_EXTRAS=llm,dataframes). docker-compose.yml passes it through for the parser/detector

also updated docs to reflect recreation of development branch on deleteion

How Has This Been Tested?

manual testing:
#install only with llm extras
docker build --build-arg LIBRARY_EXTRAS=llm -t detectmate:llm-test .
--> openai there, polars runtime is not

#install with no extras
docker build --build-arg LIBRARY_EXTRAS="" -t detectmate:base-test .

no build args behaves like full:
docker build -t detectmate:full-test .

for pkg in openai tiktoken pandas polars-runtime-compat; do
docker run --rm detectmate:full-test python -m pip show "$pkg" >/dev/null && echo "$pkg: present (expected)" || echo "UNEXPECTED: $pkg missing"
done

also works with passing through docker compose:
LIBRARY_EXTRAS=llm docker compose build detector
