## Summary
- Adds `/roadmap` page with visual flowchart showing codeflash-python
and codeflash-agent planned work
- Gated behind `isTeamMemberCheck` (same auth pattern as
`/observability`)
- Sidebar link visible only to team members
- Status tracking with distinct visual treatments: compact left-accent
for shipped, hero cards with glow for in-progress, dashed wireframe for
planned
## Test plan
- [ ] Visit `/roadmap` as a team member — page renders with status cards
- [ ] Visit `/roadmap` as a non-team member — redirects to `/`
- [ ] Sidebar shows roadmap link only for team members
- [ ] Build passes (`npm run build`)
- [ ] All tests pass (`npm test` — 39/39)
