Covers files missed by the first pass (.svelte/.astro components, bare org and
profile links, plugin doc headers), plus content that needed rewriting rather
than a URL swap: the chezmoi bootstrap script now provisions SSH for
git.swaits.com (User git, port 2222) and initialises from Gitea.
Link labels were updated to match their new targets.
Rewrites lingering github.com / *.sr.ht references to this Gitea instance,
translating GitHub and Sourcehut URL shapes to Gitea's (/blob/<ref>/ and
sr.ht /tree/<ref>/item/ -> /src/branch/<ref>/, /tree/<tag> -> /src/tag/<tag>,
/actions/workflows/X -> /actions?workflow=X, /edit/ -> /_edit/).
Left pointing at the old hosts on purpose: pull-request links (PRs were not
migrated), forks that were never migrated, and GitHub-only surfaces Gitea
lacks. OpenPGP identity proofs are untouched by design.
