Replace synchronous `readFileSync` with `fs.promises.readFile` and `Promise.all` to read CSS files in parallel during application startup. This avoids blocking the main thread and allows the event loop to process other tasks, improving perceived startup performance and responsiveness. The logic also ensures that: - File reading happens in parallel. - Order of CSS insertion is preserved by awaiting all reads and then inserting in order. - IPC calls to `insertCSS` are non-blocking (fire-and-forget), maintaining low latency. - Code hygiene is improved by not mutating the global file list.

💡 What: Replaced the synchronous
readFileSyncloop for loading CSS files insource/index.tswith asynchronousfs.promises.readFilecombined withPromise.all.🎯 Why: The original implementation blocked the main thread during startup to read multiple CSS files from disk sequentially. This could cause UI freezes or delays in processing other events during the critical
dom-readyphase.📊 Implementation Details:
