update check

The desktop app polls this endpoint for new releases. It returns a Tauri v2 updater manifest; the per-target bundle is served from R2 over the same origin. Signatures are placeholders until release artifacts are signed with scripts/sign.mjs.

GET /check?target={{target}}-{{arch}}¤t_version={{current_version}}

# 200 → newer release (per-target: version, pub_date, url, signature, notes)
# 204 → up to date
# also: GET /manifest.json  (full static manifest)
