[deep-report] Refactor oversized CJS files in actions/setup/js/ to reduce architecture debt

[github-actions]

The Architecture Violations detector (#27367) flagged 8 CJS files exceeding 1,000 lines, with the largest at 1,779 lines (create_pull_request.cjs). The full list:

File	Lines
actions/setup/js/create_pull_request.cjs	1,779
actions/setup/js/log_parser_shared.cjs	1,703
actions/setup/js/handle_agent_failure.cjs	1,590
actions/setup/js/update_project.cjs	1,451
actions/setup/js/safe_output_handler_manager.cjs	1,321
actions/setup/js/sanitize_content_core.cjs	1,224
actions/setup/js/runtime_import.cjs	1,022
actions/setup/js/safe_outputs_handlers.cjs	1,009

Each file should be split into focused modules of < 500 lines each. For example, create_pull_request.cjs can have PR validation logic, conflict-resolution helpers, and body-formatting utilities extracted into separate files.

Expected Impact: Reduces architecture violation count from 31+ to 0 for the file-size category, improves code reviewability, and reduces the surface area for agent-introduced bugs.

Suggested Agent: General-purpose coding agent (JavaScript/CJS)

Estimated Effort: Medium (1–4 hours per file, can be batched) — mechanical extraction with no behavior change.
