mithral df740d3e1a Phase 5: job queue and metadata providers
- jobs: a table-backed queue in the same SQLite file. No Redis, no second
  process, included in the same backup. claim() is a single UPDATE...RETURNING
  so a job cannot run twice even with several workers. Failures back off
  exponentially; a missing handler fails permanently rather than retrying a
  bug.
- metadata: Provider interface plus Open Library and Google Books (both
  keyless). The enricher tries providers in registration order, falls back on
  empty, and continues past a provider error.
- migration 0004: metadata_fetch records the attempt, not just the match, so a
  rescan does not re-hammer a rate-limited API for an item that will never
  match. Errors are always retried; ok/notfound are cached for 30 days.
- enrichment writes provider_ids, updates title/year, links authors through
  people/item_people, and downloads the cover as an asset. The cover download
  runs outside the transaction: a slow image host must not hold a write lock.
- endpoints: queue enrichment per library, and inspect an item's matches.
- web: Enrich button per library.

Verified live against Open Library: "The Hobbit" matched /works/OL27482W,
title and year 1937 written, a 301x500 JPEG cover downloaded and served.

Vellum web

Svelte 5 + Vite + TypeScript single-page app. It is built to a static bundle in dist/ and embedded into the Go binary, so all asset paths are relative (base: './' in vite.config.ts).

Commands

pnpm install
pnpm dev      # dev server on :5173, proxying /api to :7788
pnpm build    # writes dist/
pnpm check    # svelte-check

Run the Go server on :7788 (make run from the repo root) and pnpm dev proxies API and health requests to it, so cookies and sessions behave exactly as they will in production.

Layout

src/
  main.ts                 entry point
  App.svelte              login gate -> shell
  app.css                 design tokens and base styles
  lib/
    api.ts                typed client; mirrors the Go handlers
    session.ts            auth + library stores
    nav.ts                view state
    components/
      Login.svelte
      Shell.svelte        nav + view switch
      Libraries.svelte    library list, create, scan, delete
      LibraryView.svelte  item grid with covers
      Reader.svelte       epub.js reader with progress sync
      Users.svelte        admin user management

The reader resumes from a spine index, which is why progress positions are integers: it round-trips through the polymorphic progress table without needing a text column.
