Browser tab title should include "ComfyUI" for tab switcher discoverability

### What problem are you experiencing?

The browser tab title doesn't include "ComfyUI" anywhere. When using a keyboard-driven tab/window switcher (Raycast, Alfred, etc.), searching for "ComfyUI" returns nothing. The only way to find the tab is by searching "localhost", which matches every local dev server running.

### When does this problem occur?

When running ComfyUI alongside other local development servers and switching between tabs/windows using a launcher or tab switcher.

### How often do you encounter this problem?

Multiple times per day

### How much does this problem affect your workflow?

Causes moderate inconvenience

### Current workarounds

Searching for "localhost" instead, then visually scanning through all matching localhost tabs to find the right one.

### Ideas for solutions (Optional)

Prefix the document title with "ComfyUI" so it's discoverable by name.

No file or test is named in the issue; start by locating the frontend entry point that sets the browser document title. Prefix the title with “ComfyUI”, then verify in a browser or tab switcher that the tab is searchable by that name alongside other localhost tabs.
