🤖 fix: persist agent status across reloads

[ammar-agent]

Generated with mux

Fixes agent status (emoji, message, URL) disappearing after page reload or compaction.

Changes

• Persist full status payload to localStorage under statusState:{workspaceId}
• Load persisted status on aggregator init; restore on reload if history lacks status_set
• Use zod schema for type-safe parsing
• Keep in-memory lastStatusUrl for URL fallback across turns

Testing

• Added unit tests for persistence through reload and compaction scenarios
• make static-check passes
