- Added BARS_PER_DAY, BARS_PER_YEAR, ANNUALIZATION_FACTOR to common::thresholds::time
- Added bars_per_day field to DQNHyperparameters (default 390.0, configurable)
- compute_epoch_financials() now takes bars_per_day parameter from hyperparams
- coordinator_extended.rs + ab_testing.rs use centralized ANNUALIZATION_FACTOR
- When switching to tick data, change one constant in common/thresholds.rs
