Updated the revamp orchestration process to enforce a strict, slice-based development approach. By breaking the 225+ page overhaul into manageable, role-based slices sourced from docs/revamp/PLAN.md, we ensure greater stability, granular verifiability, and safer deployments.

This update adds a collection of standardized skills to manage the overhaul of the SparkMentis application systematically. These skills provide a structured process for auditing, planning, designing, and safely deploying changes in manageable 'slices', including dedicated tools for stability checks, feature audits, and a new portable 'design-sense' skill for broader product work. This framework is designed to keep releases small, verifiable, and consistent across the entire platform.
