Description

fix: prevent context token counter flickering during API requests

Maintains the last valid context token count between API requests by:

• Adding tracking of last valid context tokens
• Using last known value as fallback when current request lacks token data
• Only updating when new valid token counts are available

This prevents the context counter from flickering to "-" during tool calls
and API request transitions, improving the UI stability.

• Bug fix (non-breaking change which fixes an issue)
