feat: integrate claude-code-base-action as local subaction (#285)

* feat: integrate claude-code-base-action as local subaction - Copy claude-code-base-action into base-action/ directory - Update action.yml to reference ./base-action instead of external repo - Preserve complete base action structure for future refactoring This eliminates the external dependency while maintaining modularity. * feat: consolidate CI workflows and add version bump workflow - Move base-action test workflows to main .github/workflows/ - Update workflow references to use ./base-action - Add CI jobs for base-action (test, typecheck, prettier) - Add bump-claude-code-version workflow for base-action - Remove redundant .github directory from base-action This consolidates all CI workflows in one place while maintaining full test coverage for both the main action and base-action. * tsc * copy again * fix tests * fix: use absolute path for base-action reference Replace relative path ./base-action with ${{ github.action_path }}/base-action to ensure the action works correctly when used in other repositories. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: inline base-action execution to support usage in other repos Replace uses: ./base-action with direct shell execution since GitHub Actions doesn't support dynamic paths in composite actions. This ensures the action works correctly when used in other repositories. Changes: - Install Claude Code globally before execution - Run base-action's index.ts directly with bun - Pass all required INPUT_* environment variables - Maintain base-action for future separate publishing 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
