Restore approved state (tree of 4effcc7 "Added LICENSE")

Roll the working tree back to the last approved shape, before the post-LICENSE span that false-greened the AFI parity matrix with symbol-presence probes and smuggled an unauthorized SQLAlchemy dependency into FastAPI's Shapes binding.

Forward commit, not a history rewrite — the six commits since 4effcc7 stay in the log as the record of what happened.

 - [ ] **Svelte 5 runes** — the Svelte target emits Svelte 4 `readable` stores; migrate to `$state`/`$derived`.
 - [ ] **Forms codegen target** — emit form clients wired to `mizanCall` from the kernel; retire the hand-written `mizan-react/src/forms.ts` and its dependence on the pre-kernel provider.
 - [ ] **Desktop example onto the generated provider** — migrate `examples/django-react-desktop-app` off the pre-kernel `MizanProvider` (`mizan-react/src/context.tsx`) so it can be retired.
-- [ ] **Cache hardening** — thundering-herd / single-flight protection, and pinning cross-language stringification of un-normalized value types (see `backends/mizan-django/src/mizan/cache/KNOWN_ISSUES.md`).
+- [ ] **Cache hardening** — purge atomicity, per-param sub-index cleanup, thundering-herd protection, RedisCache coverage (see `backends/mizan-django/src/mizan/cache/KNOWN_ISSUES.md`).
 - [ ] **Package READMEs** — `mizan-base`, `mizan-codegen`, and the other packages missing one (see `ISSUES.md`).
