feat: Implement Sequence Compiler for data-driven choreography

Adds a 'seq_compiler' tool that converts a text-based timeline (assets/demo.seq) into a generated C++ file. This allows editing effect sequences and timing without modifying engine code. Replaces manual sequence creation with a generated 'LoadTimeline' function.
