Is there a reason to remove .minor?

[Rich-Harris]

No — these should only be visible with --verbose. Rather than changing all these I think it would be better to have a single builder.log at the end of the process like

Wrote site to "${pages}"

or

Wrote pages to "${pages}" and assets to "${assets}"

[iacore]

Mostly because how verbose vite's output is when building the site (listing every file built).

Thank you — per #3264 (comment), I think we should just add a message at the end. Closing this in favour of #3274
