- Remove console StreamHandler from get_logger() — say() already handles
console output via click.echo(); having both caused every message to
appear twice
- Move GRM_LOG_LEVEL filtering into ui.say() via _console_level() so
console verbosity is still user-controllable while the log file always
captures everything at DEBUG
- Remove [GRM] prefix from say() calls — no longer needed without
duplicate logger output, giving cleaner user-facing messages
- Update test_logging_config.py: remove console handler tests and
_level_from_env tests (now in test_ui.py), expect 1 handler only
- Add test_ui.py coverage for _console_level and say() level filtering
- Update README to document single-path console output via click.echo
- 116 tests, 100% coverage, pyright clean, ruff clean
