Note

Refactors the AI E2E tag selector into a modular TypeScript architecture with tool handlers and centralized tag configuration, adding a CLI entry and documentation.

• E2E AI Tag Selector (modularization):
  • Architecture split: Introduces analysis/, tools/, prompts/, utils/, config/ with selector.ts as orchestrator and shared types/.
  • Tools: Adds handlers for read_file, get_git_diff, get_pr_diff, find_related_files, finalize_decision with a tool registry and executor.
  • Prompts: Adds system and agent prompt builders.
  • Analysis: Adds file categorizer, decision parser, and tag analyzer (test file counting and split calculation).
  • Utils: Adds git utilities, input validation, and output formatter.
  • CLI: New index.ts; legacy e2e/scripts/ai-e2e-tags-selector.ts reduced to thin entry/export wrapper.
• Tags configuration:
  • Centralizes smoke tags via aiE2EConfig in e2e/tags.js (single source of truth with descriptions); exports for selector use.
• Docs:
  • Adds README.md detailing architecture, usage, and extension guidelines.
