Every push runs ruff, prettier, pytest and svelte-check; a tagged release runs the
blocking half again before it publishes an image. eslint and svelte-check report
without failing, since 87 and 30 findings predate the workflow.
Tagging v* builds both images on Gitea Actions and pushes them to the instance
registry, then smoke-tests the published stack. The frontend read its backend
URL through import.meta.env, which Vite resolves at build time, so an image
could only point at whatever the build host had; it now reads it at runtime.
Reads metadata.db and copies the books into a library — from a zip uploaded on
the library settings page, or from a path with `litestar calibre-import`. The
source is never touched, and re-running only picks up what is new.
Also names the formats mimetypes does not know: a Calibre library is full of
MOBI and AZW3, and a null content type used to fail the book endpoint.
