Some from Claude, I filtered some out:

1. GetListing() behaviour change (pkg/domain/service/template/template.go)
   • The old implementation returned all walk entries; the new one filters to files only (if !d.IsDir()).
   • Any caller that relied on directory entries being included in the listing will silently break. This needs verification that no callers depend on that behaviour, or a comment explaining the intentional change.
2. ProcessTemplate() strips .tmpl suffix unconditionally
   • strings.TrimSuffix(filename, ".tmpl") is applied to output filenames. This is correct for the renamed go.mod.tmpl files, but if any template file in templates/ does not have a .tmpl extension, this is a no-op and fine. However, if a non-template file happened to end in .tmpl for other reasons, it would be silently renamed. Low risk, but worth a comment.
3. go.mod template version inconsistency
   • Template go.mod.tmpl files were bumped to go 1.25 for most archetypes. Confirm this is intentional — generated projects will require Go 1.25, which users must have installed.
4. Panic in template.New() — pkg/domain/service/template/template.go
   panic("templates directory not found: " + err.Error())
   A panic at startup is acceptable for a fatal misconfiguration, but this should ideally return an error to main and exit cleanly with a message, rather than a panic stack trace presented to the end user.
5. Silent error discard in findModuleRoot()
   dir, _ := os.Getwd()
   f os.Getwd() fails (e.g., deleted working directory), dir will be empty and the loop will silently fail to find go.mod. The function should at minimum log a warning or return an error sentinel.
6. docs/layouts/index.html copyright still reads ©2018 — trivial, but it's been in place since the original and this PR touches the file; a good opportunity to update it.
7. docs/content/recipes/hosting/github-pages.md — the recipe now uses hugo-version: 'latest' instead of a pinned version (0.87.0). This is more maintainable, but latest in CI can introduce surprise breaking changes for users following the recipe. Consider recommending a minimum version comment. We should use the org one here
8. release.yml still uses GITHUB_TOKEN: ${{ secrets.GH_ACCESS_TOKEN }} — this uses a PAT secret rather than the built-in GITHUB_TOKEN. That's fine if required for cross-repo operations, but if it's only needed for the release itself, the default GITHUB_TOKEN with appropriate permissions would be preferable and simpler.
9. There are no new tests for the embed.FS migration path or findModuleRoot(). Given this is a significant behaviour change in the template service, at minimum a smoke test verifying New() can locate and enumerate templates would add confidence.
