Overview

Define and execute the migration strategy for prompt assets between .github/prompts/ and root prompts/.

Goals

1. Establish canonical prompt boundaries.
2. Execute migration with explicit mapping, refactoring, and validation.
3. Prevent path breakage with deprecation guidance and updated indexes.

Acceptance Criteria

• Final prompt matrix approved.
• Approved move set refactored to root standard.
• References and discoverability updated in both prompt directories.
• Validation completed for formatting, links, and smoke usage paths.
