Add BOC-aware lock detection and E1C-aided tracking

+The BOC lock detector parameters are part of `TrackingConfig`. The defaults use
+25 noncoherent power epochs, three confirmations, and the configured
+`loss_of_lock_epochs` for sustained failure. Carrier and BOC central/outer
+shape thresholds have explicit entry and exit values. `lock_signal_loss_power_ratio`
+sets the five-tap power loss test. These parameters affect monitoring and
+reacquisition only; they do not change discriminator or loop-filter coefficients.
+`boc_side_peak_coherence_enter/exit` calibrate the coherent E/L-to-P tap-sign
+test needed to distinguish the negative half-chip BOC sidelobe from the main
+peak using more than magnitude-only information.
