Catch missed content edits from tree restructure

The fe39fcb commit captured the file moves (git mv stages those automatically)
but didn't catch the content edits I made afterward — npm package rename
(@mizan/runtime → @mizan/base), path updates in Makefile/Dockerfile/examples,
and doc updates were all left unstaged at commit time.

This commit lands those:
- npm rename: 3 frontend package.jsons (base/vue/svelte) + mizan-base/src/index.ts + 4 codegen templates
- path updates: Makefile, Dockerfile.test, two Gitea workflows, four example/harness configs
- doc updates: CLAUDE.md, ROADMAP.md, ISSUES.md, docs/AFI_ARCHITECTURE.md
