fix: remove await from HMR server check for Windows 10 F5 debugging

[indiesewell]

Summary

This PR fixes a Windows 10 specific issue where F5 debugging was being blocked by an unnecessary await in the HMR (Hot Module Replacement) server check.

Problem

On Windows 10, the F5 debugging workflow was experiencing delays due to an awaited axios call when checking if the local development server was running. This caused unnecessary blocking behavior during the debugging process.

Solution

Removed the await keyword from the axios.get() call in the HMR server check, allowing the check to run asynchronously without blocking the debugging workflow.

Changes Made

• File Modified: src/core/webview/ClineProvider.ts
• Change: Removed await from axios.get(\http://${localServerUrl}`)` call
• Impact: Non-blocking HMR server check during F5 debugging

Technical Details

Before

try {
    await axios.get(`http://${localServerUrl}`)
} catch (error) {
    vscode.window.showErrorMessage(t("common:errors.hmr_not_running"))
}
