Fixes #425.

In start mode dev, a stylesheet shared by the entry graph and a lazy component now keeps its first position in <head>, as in production. Before, it moved after the lazy component's own styles, so equal-specificity overrides in the lazy component lost.

Changes

• The dev shell renders the shared stylesheet twice. When both copies are server-rendered, the dev style patch now removes the later copy instead of the earlier one.
• The patch now skips style tags that were already removed. Before, when both copies arrived in one mutation batch, the patch removed both of them.
• When only one copy is server-rendered, the behavior is unchanged. That copy is removed and the tag Vite manages stays.

Testing

• Added examples/start-ssr/test/style-patch.mjs. It runs the patch in jsdom for streamed copies, batched copies, and both orders of a server-rendered tag and a Vite tag.
• The streamed and batched cases fail without the fix.
• Reproduced the issue in headless Chrome with the files from the issue. After the fix, .corner resolves to position: absolute, and editing button.css still hot-updates it.
• examples/start-ssr suite (node test/run.mjs) passes 749/749. pnpm test:unit passes.
