Dependency Update Review: preact 10.28.3 → 10.28.4

Update Summary

Dependency	Old Version	New Version	Bump Type
preact	10.28.3	10.28.4	Patch

What Changed in preact 10.28.4

Bug Fix:

• Fixed crash when a synchronous effect render unmounts the tree (#5026) — edge case where calling render(null) inside a useEffect would cause a crash

Size Optimizations (internal):

• forEach → some pattern throughout hooks and diff code for smaller bundle size
• Consolidated conditionals in diff logic
• Refactored renderComponent to check _dirty flag inside condition block

All changes are internal implementation details — no public API changes, no signature changes, no behavioral changes to documented functionality.

Codebase Impact Analysis

Files using preact:

File	Usage	Risk
embed/src/index.tsx:1	render from 'preact'	None — public API unchanged
embed/src/components/App.tsx:1	useCallback, useEffect, useState	None — hooks API unchanged
embed/src/components/CommentForm.tsx:1	useEffect, useState	None
embed/src/components/Comment.tsx:1	useState	None
embed/src/components/GitHubLoginButton.tsx:1	useCallback	None

The codebase uses only public preact APIs. None of the internal changes affect this usage. The bug fix addresses an edge case (unmounting tree from within an effect) that this codebase doesn't exercise.
