fix: add explicit roadmap approval gate before committing

- Present proposed roadmap nicely inline (table + phase details)
- Use AskUserQuestion to confirm before committing
- Options: Approve, Adjust phases, Review full file
- Loop on adjustments until user approves

Previously, roadmap was committed immediately without user review.
