[Good first issue]: Add page metadata to /organizers

[FrankezeCode]

Summary

The city organizers directory has no page-specific metadata. Add SEO-friendly title and description for the public organizers list.

What should change?

[ ] Add metadata to src/app/organizers/page.tsx or a route layout
[ ] Title example: City Organizers | BetterDev
[ ] Description: mention city co-leads and local meetups

Acceptance criteria

• Organizers directory has custom title and description
• Page functionality unchanged
• Build passes

How to test

1. Open /organizers
2. Verify tab title and meta description
3. Confirm organizer list still loads
