Phase 2: carrier-frequency acquisition and what it leaves behind

Test	What it does	Result
test_offset_floor_is_the_walk	A 10 kHz laser pair's Wiener walk, not the estimator, sets the offset residual: it matches to 0.1 Hz with 10 MHz present or absent.	✅ pass
test_offset_is_acquired	Coarse acquisition keeps v_err within 5% of the no-offset run at 0.39, 1.17, 10 and 45 MHz, past the unwrapper's $\pm \pi$ ambiguity at half a cycle per 32-symbol block.	✅ pass
test_offset_is_reported	With the lasers noiseless SimOut.cfo returns the offset to 0.1 Hz from 100 kHz to 45 MHz, past coarse acquisition's 781.25 kHz grid.	✅ pass
test_offset_past_nyquist_refused	run_symbols refuses an offset at or past $R/2$, where one sample per symbol aliases $f+R$ onto $f$.	✅ pass
