build: install with uv rather than pip, and stop shipping the installer - #12
Conversation
`pip install /packages` is replaced with `uv pip install`. Deliberately not `uv sync`, which was the first instinct: sync makes the environment *match* a lockfile, and this layer installs on top of the base image's /opt/venv, which already holds extralit-server. Sync would uninstall every server package absent from a lockfile this repo does not even have. `--python /opt/venv/bin/python` names the target venv rather than relying on VIRTUAL_ENV, which only recent base images set, so this keeps working against an older `EXTRALIT_SERVER_IMAGE`. uv and the pyproject arrive as bind mounts, so neither is left in a shipped layer and the `rm -rf /packages` cleanup is no longer needed. UV_COMPILE_BYTECODE matches the base image, so a worker's first import does not pay to compile these too. `chmod +x` folds into COPY --chmod. Verified by building the whole image against a locally built server base: 4 packages installed (honcho, pymupdf, pymupdf4llm, and the shim), the server's own rq/redis/httpx untouched, uv and /packages absent from the result, and the inherited retrieval payloads still load.

dependencies from the mounted pyproject.toml as a requirements file using -r,
rather than treating /packages as a local project path; keep the existing Python

Two patterns borrowed from astral-sh/uv-docker-example's multistage.Dockerfile. PYTHONUNBUFFERED is the one that earns its place. honcho gives each process a pipe rather than a tty, so Python block-buffers into it, and a Space's logs are the only way to see a crash. Demonstrated in the built image: a worker that prints a line and is then SIGKILLed — the shape an OOM takes here — loses that line entirely without this, and keeps it with. UV_PYTHON_DOWNLOADS=0 changes nothing today, and the commit should not pretend otherwise: with an explicit `--python`, uv reports the same error either way. It guards a seam this PR deliberately created — `--python` is spelled out so the build tolerates a base image predating VIRTUAL_ENV, and if someone later drops the flag in favour of that variable against an older base, uv would be free to fetch its own interpreter and install into something that is not the server's venv. Cheaper to forbid than to debug. Deliberately not borrowed: UV_NO_DEV, verified to be a no-op here because `uv pip install <path>` does not install PEP 735 dependency-groups (confirmed: ruff/pytest/rq-dashboard absent from a clean install). The example's builder-stage layout and `uv sync --locked` do not transfer either — this image layers into an inherited venv rather than building one, and its separate no-uv stage is already achieved by bind-mounting uv. Rebuilt against a local server base: still 4 packages, deps import, smoke 4/4, and UV_PYTHON_DOWNLOADS correctly does not leak into the shipped image's environment.
Addresses CodeRabbit on PR #12. `uv pip install /packages` treated the mount as a local project and built this repo as a package, but `packages = ["extralit_ocr"]` is not under the mount — only `pyproject.toml` is. It did not fail, so the reviewer's stated risk is not the reason to change it. The real one is what it produced: an `extralit-hf-space` dist containing eight dist-info files and no code at all, whose build succeeded only because hatchling tolerated a packages directory that was not there. `extralit_ocr` is imported from /home/extralit via the working directory honcho runs in, never from site-packages, so that dist was never load-bearing. `-r /packages/pyproject.toml` installs the dependencies and nothing else. Rebuilt against a local server base: 3 packages instead of 4, the phantom dist gone, extralit_ocr still imports from /home/extralit, server and inherited retrieval payloads untouched.
