feat(cloud): Add telemetry retry queue for network resilience

[daniel-lxs]

Summary

Implements a retry queue for cloud telemetry events to prevent data loss during network failures.

Changes

• Add RetryQueue class with workspace-scoped persistence
• Queue failed telemetry events for automatic retry
• Retry events every 60 seconds with fresh auth tokens
• FIFO eviction when queue reaches 100 events
• Persist queue across VS Code restarts

Implementation Details

• RetryQueue: Manages failed requests with persistence and automatic retry logic
• CloudTelemetryClient: Integrates retry queue to catch network errors
• CloudService: Initializes retry queue with auth header provider

Testing

• All existing tests pass (229 tests)
• Added 8 new tests for RetryQueue functionality
• TypeScript compilation successful

Context

This feature was migrated from RooCodeInc/Roo-Code-Cloud#744 to ensure telemetry data isn't lost during network failures or temporary server issues.

The retry queue activates when telemetry events fail due to network errors. Events are retried until successful or evicted by newer events.

Important

Introduces RetryQueue for retrying failed telemetry events in CloudTelemetryClient, with persistence and auth state handling.

• Behavior:
  • Introduces RetryQueue to handle failed telemetry events in CloudTelemetryClient.
  • Retries events every 60 seconds with fresh auth tokens.
  • Supports FIFO eviction when queue reaches 100 events.
  • Persists queue across VS Code restarts.
  • Handles network errors, server errors (5xx), and rate limiting (429).
  • Does not retry on client errors (4xx) except 429.
• Integration:
  • CloudService initializes RetryQueue with auth header provider.
  • CloudTelemetryClient uses RetryQueue to queue failed requests.
• Testing:
  • Adds 8 new tests for RetryQueue functionality.
  • Ensures queue handles auth state changes, network errors, and rate limits.
• Misc:
  • Exports RetryQueue and related types in index.ts.
