Persist GitHub login preference to avoid repeated prompts

[Aanderson1998]

Description

Implement logic in the Coding Agent so that when a user declines GitHub authentication the first time, the decision is stored and the prompt is not shown on subsequent launches. Ensure persistence across sessions and repositories as discussed.

Technical Requirements

• Introduce a persistent storage mechanism (config file or local DB) to record user's GitHub auth choice
• Detect existing stored preference on startup and suppress prompt accordingly
• Ensure solution works across multiple repositories and sessions
• Provide a way to reset/override the stored decision if needed (e.g., CLI flag or config reset)

Background Context

Meeting Source: Coding Agent discussion on July 23, 2025
Project Context: coding-agent - The Coding Agent demo requires smoother UX without repeated auth prompts.

Acceptance Criteria

• User sees GitHub auth prompt only once per environment unless reset
• Preference persists across agent restarts and repo changes
• Unit tests cover preference save/load logic
• Documentation updated (README) explaining preference storage and reset

Dependencies & Blockers

• None identified

Additional Notes

This feature will improve demo experience and user satisfaction.
