Change integrated prompts to -apm suffix

[danielmeppiel]

This pull request updates the prompt integration naming convention from an @ prefix to a -apm suffix, improving discoverability and avoiding conflicts in VSCode and Copilot. The change affects prompt file generation, .gitignore patterns, documentation, and all related tests to ensure a consistent and intent-first naming approach.

[Copilot]

Pull Request Overview

This pull request migrates the prompt integration naming convention from an @ prefix (e.g., @accessibility-audit.prompt.md) to a -apm suffix (e.g., accessibility-audit-apm.prompt.md). The change improves VSCode autocomplete discoverability and avoids symbol conflicts with Copilot's @ agent syntax.

Key Changes:

• Updated core filename generation logic in PromptIntegrator.get_target_filename() to use -apm suffix pattern
• Modified .gitignore pattern from @*.prompt.md to *-apm.prompt.md
• Added comprehensive test coverage for the new suffix pattern with edge case validation
