Feature Request: Link Preview Metadata for Custom Domain

[Lucas-almma]

What happened?

Description
When sharing a custom domain URL that's running LibreChat, the link preview (unfurled content) displays generic LibreChat metadata instead of the custom domain's branding.

Current Behavior
The link preview shows:

Title: "LibreChat"
Description: "LibreChat - An open-source chat application with support for multiple AI models"
The domain name itself is correct, but all other metadata comes from LibreChat's defaults.

Expected Behavior
The link preview should show appropriate metadata specific to the custom domain and branding rather than generic LibreChat information.

Possible Cause
This appears to be related to incorrect or default Open Graph (og:) meta tags in the HTML. When deploying LibreChat to a custom domain, the site seems to retain LibreChat's default metadata instead of allowing customization.

Additional Information
This affects user perception and branding when sharing links
Link previews are generated from meta tags in the page's HTML header

Suggested Fix
Add configuration options in LibreChat to allow customization of:

og:title
og:description
og:image

I noticed this as well. A branded link preview would be nice. Also with the correct favicon.
