feat: add report.no_time config option for automatic modes

Add YAML section `report.no_time` that controls `--no-time` behavior
in automatic modes (`--commit`, `--send`). CLI flag `--no-time`
always wins. Manual `--output` ignores the YAML setting.

- Config.get_report_no_time() reads the YAML value (defaults to false)
- cli._resolve_no_time() encapsulates CLI > YAML priority
- --init-config now generates the report section
- docs updated in README.md and docs/CONFIG.md

Closes #49
