feat(release): show notes and assets, upload with --clobber, download like gh

release view printed "v0.1.0 v0.1.0" and a URL: the notes and assets
were only in --json. It now shows the title and tag, a Latest,
Pre-release or Draft badge, who released it when and the target, the
assets with their sizes and the notes, rendered on a terminal. Without
a tag it shows the latest release, and --web opens it.

release asset upload silently attached a second asset with the same
name; it now refuses unless --clobber replaces the existing one.
release delete printed the deleted release as a live row; it reports
"✓ Deleted release v2.0.0 ... (tag kept; use --delete-tag)".

release list shows TITLE, TYPE, TAG and PUBLISHED. release create takes
asset files after the tag, -t/-n/-F/-e/-d/-p (--body and --body-file
still work) and the new alias. Downloads select assets by name or ID or
with --pattern, default to every asset of the latest release, write to
./NAME, --dir or --output with --clobber/--skip-existing, and --archive
fetches the source code. release upload and release download are
shortcuts for the asset commands, asset edit and delete take names or
IDs, and the release JSON gains author and assets.
