Remove unused imports (F401) and duplicate/shadowed import redefinitions (F811) across the codebase using ruff's safe autofixes. No behavioral changes -- imports only. - ~1400 safe autofixes applied across 644 files (net -1072 lines) - __init__.py re-exports preserved (excluded from F401 removal so public re-export surfaces stay intact) - Re-exports that are imported or monkeypatched by tests but look unused in their defining module are kept with explicit # noqa: F401 (gateway/run.py load_dotenv; run_agent re-exports from agent.message_sanitization, agent.context_compressor, agent.retry_utils, agent.prompt_builder, agent.process_bootstrap, agent.codex_responses_adapter) - Unsafe F841 (unused-variable) fixes deliberately skipped -- those can change behavior when the RHS has side effects - ruff lints remain disabled in pyproject.toml (only PLW1514 is selected); this is a one-time cleanup, not a config change Verification: - python -m compileall: clean - pytest --collect-only: all 27161 tests collect (zero import errors) - core entry points import clean (run_agent, model_tools, cli, toolsets, hermes_state, batch_runner, gateway) - static scan: every name any test imports directly from an edited module still resolves

"""Tests for _web_ui_build_needed — staleness check for the web UI dist.

Critical invariant: the Vite build outputs to hermes_cli/web_dist/

The sentinel must be checked in the correct output directory or the
