📄 Description

Refs #126. Follows #141.

Problem: pymupdf==1.28.2 ships a musllinux_1_2_x86_64 wheel and a manylinux_2_28_aarch64 wheel, but no musl/aarch64 wheel. On alpine/arm64, uv falls back to building from source, and that build fails, so the alpine arm64 image never builds.

Change: on alpine/arm64 only, Dockerfile.alpine passes --no-install-package pymupdf, keyed on BuildKit's TARGETARCH.

What that image loses: only Zotero PDF text extraction. pymupdf is imported lazily in _extract_pdf_text, which raises a clear ImportError without it. Every other image keeps pymupdf.

Tested by building natively on arm64 with docker buildx build --platform linux/arm64 -f Dockerfile.alpine .:

The build succeeds.
oikb --version prints 0.5.0.
pyzotero is installed and fitz isn't.
