Two new React Compiler compat hazards:
- discarded-subscription: a useSyncExternalStore call whose result is thrown
away, so the reads after it get cached on unrelated inputs.
- store-read-in-memo-block: a render-level getState() that the compiler places
in a cache-guarded block. Reads inside the source's own useMemo or callbacks
keep their written deps and are skipped.
The compiled output is parsed once for hook and store reads. Current sites are
grandfathered in the hazard baseline.

Adds oxc-transform-react as a devDependency and a ratchet that runs React
Compiler in analysis mode over the shipped renderer sources. Files can't gain
bailouts (new files must compile fully), and new code the compiler would run
differently is banned: hooks it memoizes into a cached block, bare `void x;`
reads, member postfix updates used as values, and "use no memo" opt-outs.
Both baselines are generated by --update / --prune.
