- Create a new document `plans/implementation-plan-A-B.md` that consolidates the implementation plans for the Python rewrite (Phase A) and the migration to Linux Mint (Phase B).
- The document includes detailed sections such as executive summary, checklist, prerequisites, step-by-step activities, architectural hooks for future phases, risk matrix, and references.
- Ensure the plan is self-contained, adhering to specified structure and style guidelines, and does not introduce new technologies or modify existing files.
