OrcaWinandOrcaWin bb368c3ae6 chore(ratchet): flag discarded subscriptions and store snapshots React Compiler would cache (#39630) ...

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.
