fix: prevent cleanup from stripping copilot-instructions.md markers before generation 

The cleanup() method was removing the BMAD marker section from
copilot-instructions.md, leaving user content without markers.
generateCopilotInstructions() then treated the markerless file as
legacy, backed it up, and overwrote user content.

Fix: remove the copilot-instructions.md block from cleanup() entirely.
generateCopilotInstructions() already handles marker-based replacement
in a single read-modify-write pass that correctly preserves user content.
