Instead of silently skipping research based on the config toggle,
plan-phase now asks the user whether to research before planning
(when no explicit --research or --skip-research flag is provided).
The prompt includes a contextual recommendation:
- 'Research first (Recommended)' for new features, integrations, etc.
- 'Skip research' for bug fixes, refactors, well-understood tasks
The --research and --skip-research flags still work as silent overrides
for automation. Auto mode (--auto) respects the config toggle silently.
