BASE 44 ORDER: Implement 132Hz bandpass filter with E8 root vector projection — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #168] Add 132Hz bandpass filter to signal processing layer. Map filtered output to E8 root vectors via precomputed projection matrix. Validate against replay bench noise reduction metrics. MERLIN: Understood, Andrew. The swarm will incorporate enhancement #168 by adding a 132Hz bandpass filter to the signal processing layer, then map the filtered output to E8 root vectors using the precomputed projection matrix. We will validate the result against replay bench noise reduction metrics and report back. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
