* craft-zip: ZIP preflight, bounded entry read and Budget (from craft-archive, #129)
The ZIP half of the craft-archive proposal (#126, #129): an allocation-free check of the end
records and central directory that runs before a ZIP reader indexes the archive, a bounded
entry read that distrusts the declared size, and the named Budget both charge. The XML half
of #129 is not carried: craft-xml bounds XML now.
* craft-zip: Archive (entry-count guard, duplicate names, budgeted reads) and Writer
check_entry_count is craft-opc's guard: the declared entry count, ZIP64 included, checked on
the raw bytes before zip parses the central directory. Archive reads entries within a per-entry
limit and a total Budget through read_entry. Duplicate names are found by counting the central
directory headers against the entries zip kept. Writer is craft-opc's ZipOut: stored or deflated
entries, ZIP64 for large ones, one fixed timestamp.
* craft-idml, craft-epub: read and write through craft-zip
Both crates drop their own bounded ZIP reads and zip writers. They gain the entry-count check
before the archive is indexed (ZIP64 included) and archives whose bytes depend only on their
content (one fixed timestamp).

* craft-epub: read EPUB 2 and 3 packages (container, package document, bounded entry reads)
The container layer of WordCraft's EPUB import (storytold/wordcraft#3119): container.xml,
the package document's metadata, manifest and spine, href resolution, and entry reads inside
per-entry and total byte budgets. Moved onto craft-xml, read strictly, and extended to EPUB 2
packages (NCX path, cover meta, dc-metadata).
* craft-epub: write EPUB 3 packages (reflowable and fixed layout)
The packaging of DesignCraft's EPUB export (crates/epub/src/package.rs at 513f77b8): the stored
mimetype, container, package document, nested navigation, fixed-layout metadata and the
derived identifier, behind a neutral Book of metadata, resources, spine and navigation. Adds
the dc:subject and dc:description metadata, the W3CDTF check and the stricter language tag
check of WordCraft's EPUB export (storytold/wordcraft#2815).
