chore(shared): strict migration batch 3b (feed, log hooks)

[rebelchris]

Summary

• continue ENG-803 strict migration in packages/shared
• fix strict typing in hooks/feed/* and hooks/log/*
• tighten callback/ref typing and query updater shapes without runtime behavior changes

Files

• src/hooks/feed/*
• src/hooks/log/*

Validation

• pnpm --filter shared lint:fix
• pnpm --filter shared lint
• pnpm --filter shared typecheck:strict (batch-3 target scope clean in combined validation)
• pnpm --filter extension typecheck ✅
• pnpm --filter shared test -- --testPathPattern="src/hooks/(contentPreference|feed|log|notifications|search|squads|translation)" ✅

Notes

• pnpm --filter shared typecheck and pnpm --filter webapp typecheck fail on existing repo-wide baseline issues unrelated to this batch in the current environment.
• pnpm --filter webapp build fails at prerender with TLS cert error (UNABLE_TO_GET_ISSUER_CERT_LOCALLY) after successful compile.

not sure event will really be instanceOf CustomEvent every time, I would use as here for now even though its not ideal

Adjusted as casting per ante's feedback

• Gather context
• Read useLogLifecycleEvents.ts and useLogPageView.ts
• Replace instanceof CustomEvent with as casting
• Commit and push

Both files had the same pattern — an instanceof CustomEvent guard before passing the event to the callback ref. Replaced with as CustomEvent cast in both:

useLogLifecycleEvents.ts (line ~59):

// Before
const callback = (event: Event) => {
  if (!(event instanceof CustomEvent)) {
    return;
  }
  lifecycleCallbackRef.current?.(event);
};

// After
const callback = (event: Event) => {
  lifecycleCallbackRef.current?.(event as CustomEvent);
};

useLogPageView.ts (line ~31) — same change applied.
