Extend Avocet to handle EEG epoch labeling for Merlin Phase C motor imagery training.

Data type: EEG epochs — 4-second windows of EEG data (channels × samples arrays) tagged with motor imagery class (left, right, feet, rest) and quality score.

Quality scorer integration: Merlin's EEG signal quality scorer flags epochs with eye blink contamination, EMG spike, motion artifact, or low SNR. Certified epochs auto-enter training set. Uncertain epochs enter Avocet review queue.

Review UI: show PSD plot per channel for the epoch, artifact flags, class label. Reviewer can: Accept / Reject / Re-label. ASMR bucket expansion pattern applies — bucket drop is satisfying.

Trainer integration: after labeling, one-click trigger runs CSP + LDA training. Progress in Avocet. Writes model to ~/.merlin/models/<profile>_eeg.joblib.

See Circuit-Forge/merlin Phase C for full EEG architecture.
