Subject: [PATCH] feat(build): append timestamp build number to dist version

Production builds now output version as '2.0.0+YYYYMMDDHHmm' in
dist/manifest.json. Source manifest.json stays at '2.0.0'.

This allows identifying exact builds without bumping the semver,
useful during development and beta testing.
