🏷️ New: metadata editing & ISBN enrichment

This release adds a meta subcommand to read, hand-edit, or auto-fill a book's metadata — including looking it up online by ISBN. The input is never modified; edits are written to <name>_meta.epub (or -o <path>).

# Print the current metadata (--json for machine output)
epublift meta show book.epub

# Edit by hand (repeat --author / --subject for multiple values)
epublift meta set book.epub --title "…" --author "…" --language tr --series "Dune:2"

# Auto-fill missing fields from Open Library by ISBN
epublift meta enrich book.epub --isbn 9780… --dry-run

Highlights

Language-aware enrichment. meta enrich resolves the book's own language (dc:language, or --lang) and matches by ISBN-13, so the title/author/publisher come back in the book's language. Fields whose language differs — e.g. English work-level subjects/description on a Turkish book — are skipped by default (override with --allow-foreign-meta). No translation is ever performed.
Fill gaps, safely. Only missing fields are filled by default (--overwrite to replace); --dry-run previews the changes; --include-description opts the (often publisher-authored) description in.
100% pure-Rust, no C. The Open Library lookup uses a hand-rolled HTTPS client on rustls + the RustCrypto provider + webpki-roots — no ring/aws-lc, no C toolchain. It's behind the opt-in metadata build feature; meta show / meta set need no network and are always available. (These release binaries are built with metadata, so enrich works out of the box.)
ISBN that readers recognize. The ISBN is written as a dc:identifier (urn:isbn:…), so Calibre and Apple Books surface it as the book's ISBN (a dc:source is provenance, not an identifier).
The companion web service (epublift-web v1.7.0) gains a matching Metadata mode — drop an .epub, optionally Fetch from Open Library, edit, and download — fully translated in all 13 UI languages.
