The alpine provider hosted only remote (proxy) repos; there was no way to publish first-party .apk packages the way rpm-local and deb-local already allow. This extends the existing alpine provider into a real apk repository: uploaded .apk files are parsed in pure Go and a per-arch APKINDEX.tar.gz is generated on demand, at parity with rpm repodata and deb Packages generation. - Implement LocalUploader/LocalIndexer/PostUploadHook/PostDeleteHook on the alpine provider, keeping the remote proxy methods intact. - Parse .apk (concatenated gzipped tar streams) in pure Go: read .PKGINFO from the control stream and compute the apk pull checksum C: = Q1+base64(sha1) over the raw control gzip stream (not the whole file). - Generate an unsigned per-arch APKINDEX.tar.gz (clients use --allow-untrusted), applying the same dot-segment normalization as deb for ./<arch>/... requests. - Add AlpineMetadata plus separate Alpine store/reader/deleter interfaces so the rpm/deb metadata interfaces are not widened. - Add the alpine_metadata table and its Insert/Delete/List DB methods. - Add testsupport.MinimalApk plus unit tests (parse, Q1 checksum, per-arch filtering, dot-segment handling, validate) and a dockere2e index test.
