diag(sp14 B.12): per-epoch pearl_egf_diag HEALTH_DIAG emit

Browse Source 
Adds a new HEALTH_DIAG[{epoch}]: pearl_egf_diag line immediately after
the aux_moe block in the per-epoch metrics section of training_loop.rs.
Reads all 13 SP14 ISV slots [383..396) — α_smoothed, α_raw, β, k_aux,
k_q, var_aux, var_q, var_α, q_dis_short, q_dis_long, gate1 state,
post_open_min, lockout — via the established read_isv_signal_at pattern,
giving forensic visibility into EGF pearl state each epoch.

gate1/gate2 sigmoid outputs are intentionally omitted: recomputing them
host-side would violate feedback_no_cpu_compute_strict; the sigmoid
inputs are sufficient for a reader to infer the output values.

docs/isv-slots.md updated (Invariant 7): records B.12 HEALTH_DIAG wire-up.

@@ -388,5 +388,10 @@ Producer + consumer wiring lands in B.3-B.12; B.1 is additive
infrastructure (slot constants), B.2 wires the 11 fold-reset registry
entries + dispatch arms — both are additive only (no behavior change).
B.12 (2026-05-05) adds the per-epoch `HEALTH_DIAG[{epoch}]: pearl_egf_diag`
emit in `training_loop.rs` reading all 13 slots. gate1/gate2 sigmoid output
values are omitted from the emit (recomputing host-side would violate
`feedback_no_cpu_compute_strict`); the inputs are sufficient for inference.
