🐛 Bug Fixes

• Patch-channel contract hardening from the stage-2 re-audit: ordinary `patchDriver` registrations unbind with their owner (entries no longer leak past unmount); merged transitions move their held-patch stash so no patch strands; the optimistic drain shares the normal drain's per-entry error isolation and boundary routing; accessor-bearing records are excluded at admission (scan-before-trust) and records that acquire accessors demote their patches to tracked effect fallbacks; writable projection arrays emit setter row ops at their fold-commit visibility moment; row-ops/slot registrations resolve chained backings to the ultimate owner; duplicate keys match occurrence-aware instead of first-wins; the production dev-token typo (`_DX_DEV_`) is fixed; `patchDriver: true` normalizes identically in Babel and the native loader, the option is typed in `TransformOptions`, and a `dom-patch` parity tier ratchets patch-mode output across both compilers (currently byte-identical on all fixtures).
• Scope-wrap bare function children in hydratable mode. A function child (`<main>{() => <App/>}</main>`, including via the `children` attribute) is a deferred hole at runtime, but it never classified as `dynamic`, so neither generate reserved an id scope for it — its owner ids drifted across async retry passes on the server and desynced from the client (the #2900 hydration-id-parity class). Both compilers now treat syntactic function expressions as scope-eligible alongside dynamic values, emitting `_$scope(...)` in the ssr generate and around the matching insert accessor in the dom generate. The native compiler also unwraps TS casts in the allocate-ids predicate, matching Babel (fixes a scope-emission desync for `{call() as any}` children).
