Add in-app notification for xAI paid model users about free Grok Code Fast

[kiloconnect]

Summary

Adds a targeted in-app notification for users who have used xAI paid models in the past 30 days, informing them about the new free optimized Grok Code Fast model.

Targeting criteria

Selects distinct users from microdollar_usage where:

• requested_model LIKE 'x-ai/%'
• cost > 0 (paid usage only)
• Usage within the last 30 days

Notification

• Title: Grok Code Fast — Now Free
• Message: Try a new, optimized version of Grok Code Fast, totally free in Kilo.
• Learn more: https://blog.kilo.ai/p/grok-code-fast-optimized
• Shows in: extension, cli

Implementation

Follows the existing conditional notification pattern in src/lib/notifications.ts (same approach as generateAutocompleteNotification). Queries microdollar_usage directly for the current user with LIMIT 1 for efficiency.
