v1.2.5 — Environment Doctor, CLI Diagnostics & Roadmap Solution Debriefs

What's Changed

🛠️ CLI & Environment Diagnostics

• Environment Doctor: Added the torollo doctor CLI command to perform comprehensive system diagnostics, verifying Docker host connectivity, port availability, and backend health status (#100).
• Improved First-Run Experience: Enhanced torollo start CLI to wait for backend initialization in real time, showing image pull progress and actionable error diagnostics if Docker is unreachable (#98).

🎓 Learning Engine & Roadmaps

• Step Solution Debriefs: Once a step's validation checks pass, learners can now view an architectural solution debrief explaining the underlying design patterns (#95).
• Cache-Aside Roadmap Recalibration: Updated the Cache-aside with Redis roadmap to 9 steps (45 mins) with enhanced completion screen metrics (#96).

⚡ Performance & UI Improvements

• Bundle Optimization: Lazy-loaded heavy frontend sections (LearningSection, RoadmapDetailPage, modal dialogs) to decrease CLI launch latency and package overhead (#99).
• Modal Portals & UI Polish: Rendered dialogs via React portals for improved layering and recalibrated completion screen layout (#96).
