[FEATURE] /simplify should cut AI slop comments

Problem Statement

AI loves to overcomment the code.

Proposed Solution

The /simplify command needs a 5th agent to find and prune oververbose comments for token efficency and performance. Eg.:

Example 1 - code is very clear, specifiation has been moved to

# Sensor values beyond 32.3 must be considered noise
sensor_values = np.clip(sensor_values, a_max=noise_limit)

Example 2 - changes are explained (commit msgs contain the justification):

# V1 version implemented RobustScaler instead of the baseline StandardScaler
# V2 version had an issue with inf values
sensor_values = normalize_v3(raw_sensor_values)
