Ignore `@types/*` packages inside optimizer

Editor assessment

Strong subject work: fix(optimizer) scopes it precisely, the glob pattern `@types/*` is backticked and unambiguous, and the mood and length are right. The redundancy of 'inside optimizer' after the scope is a small wart — the scope already says optimizer, so that phrase could be trimmed. The footer 'fix #804' follows a correct blank line and GitHub recognizes 'fix' as a closing keyword, though the trailer-canonical 'Fixes: #804' would satisfy stricter footer parsers and keep references out of the headline per spec convention. No body explaining why type-only packages break pre-bundling — presumably resolution failures — which is the interesting 'why' here. Overall a solid, well-executed fix message with minor formatting polish available.
