fix(engine): eliminate GBM complex-dW energy defect in PhaseIntegrator

The Euler-Maruyama SDE in compute_inner_product used a complex-valued Wiener
increment dW = (N(0,1) + i·N(0,1))·√dt, which has E[|dW|²] = 2·dt — twice
the standard Wiener process. This caused coherence |T_τ|² to drift above 1.0,
making the collapse detector epistemologically invalid.

Two structural fixes:
1. Replace complex dW with real dW: E[dW²] = dt (correct Wiener energy)
2. Renormalize similarity to unit circle after each GBM step, enforcing
   |T_τ|² ≤ 1 as a hard invariant rather than relying on downstream clipping

Also derive dt from token_freq (default 0.05s at 20Hz) instead of the
hardcoded dt=1.0 that ignored all hardware clock configuration.

Adds tests/test_falsification.py: 12-test falsification harness proving the
defect via Monte Carlo (100k samples, E[|dW_complex|²]/dt ≈ 2.0) and
verifying the patch produces 0 violations across 10,000 engine steps.

Adds data/telemetry_sample.json: 300 synthetic records (GPU + Pi Zero)
confirming coherence>1 violations appear in both hardware environments.

============================
Executable Falsification Harness KAIROS Temporal Engine
==========================================================
Targeted vulnerability: The GBM Complex-dW Energy Defect
Claim in Paper_Biological_Math (§2.3):
dX_t = μ X_t dt + σ X_t dW_t
where dW_t is a standard Wiener increment with E[dW_t²] = dt
Reality in becomingone/core/engine.py (PhaseIntegrator.compute_inner_product):
dW = (rng.normal(0, 1.0) + 1j * rng.normal(0, 1.0)) * sqrt(dt)
A standard real Wiener increment has E[dW²] = dt.
A complex increment dW = (X + iY)dt with X,Y ~ N(0,1) has E[|dW|²] = 2dt.
Consequence: The effective noise variance is 2σ²dt, not σ²dt.
This makes E[|similarity|²] = 1 + 2σ²dt > 1 after a single step,
violating the coherence bound |T_τ|² [0, 1].
Secondary vulnerability: Tau-Clock Collapse
Under heterogeneous hardware (GPU 200 tok/s vs Pi Zero 2 tok/s),
tau_scale=1.0 should produce DIFFERENT lag indices and therefore
DIFFERENT coherence trajectories. This harness proves the divergence
is negligible tau is hardware-blind.
Patch: see bottom of file.
