- bunext build records when each page's client bundle hash last changed
in .bunext/page-lastmod.json (sitemap.lastmod_file to relocate). The
hash covers the page's whole import graph, so component edits re-date
every page that uses them. The sitemap uses these dates as lastmod
- Add sitemap.default_lastmod
- BREAKING: use_file_lastmod now defaults to false (file mtimes are reset
by checkouts); it is a fallback after the build record
- Warn when a page or __root.tsx is skipped because its default export
is not at the start of a line (e.g. export { Page as default })
- Replace leaking module mocks in tests (log, grab-root-file-path) with
spies and fixtures
