H000018 Oddball MMN/P3

HTML/browser preview of the three-stimulus Oddball task built with psyflow-web.
The standard/deviant/target trial semantics, target-only response rule (space), and block-level MMN/P3 metrics are aligned to local T000018-oddball-mmn; block count is shortened for preview.

Layout

• main.ts: task orchestration
• config/config.yaml: declarative config
• src/run_trial.ts: trial logic
• src/utils.ts: condition generation and metrics helpers
