Introduce three helper lemmas in StraightLine.lean that bundle the common 8-step proof pattern into 2-3 step proofs: - straight_line_transfer_final: T instruction final value - straight_line_zero_final: Z instruction final value - straight_line_preserves_final: register preservation Also moves straight_lineFinalState_eq_of_halted from Composition/Helpers to StraightLine.lean where it belongs. Refactors 18+ theorems across PrimitiveRecursion/Preservation.lean and Minimization/Preservation.lean to use these helpers, reducing total line count by ~80 lines.
