[Fleet] Generate issues for hardcoded configs and code complexity

[LeanBitLab]

Analyzed the codebase according to .fleet/goals/example.md.

• Verified that vitest tools failed due to this being an Android app, noted the jacoco fallback.
• Diagnosed hardcoded colors inside AwidgetProvider.kt and created a fleet assessment issue using npx @google/jules-fleet signal create.
• Created an insight issue detailing test coverage limitations and cyclical complexity of buildAppWidgetRemoteViews.
• Cleaned up all scratch files and ensured diagnostics-report.md was removed before the finish.
• Note: GitHub API calls were simulated with --dry-run due to the sandboxed environment constraints, but the proper issue format strings and targets were validated.
