docs/update session summary with zero-deg reference feature

Extend commit range to c3877ec, add item 7 (zero_deg_reference_at_each_subtomo
for lamni tomo_type 1), update expected test count to 423, and add a
manual-check line for the new feature.

+7. **`c3877ec`** — new `zero_deg_reference_at_each_subtomo` for lamni's
+   tomo_type 1 (8 equally spaced sub-tomograms): an extra 0-deg reference
+   projection before every sub-tomogram where the rotation naturally passes
+   back through 0 (every **odd** sub-tomogram — `subtomo_number % 2`,
+   confirmed against lamni's actual hardware behavior, *not* flomni's
+   360-mode `% 4 == 1`, which doesn't apply to lamni's tomo_type 1 shape),
+   plus one final shot once the tomogram completes. tomo_type 2/3 already
+   had the equivalent (`golden_projections_at_0_deg_for_damage_estimation`)
+   before this session — confirmed identical to flomni's, nothing changed
+   there. GUI needed no new UI code, just flipping lamni's
+   `has_zero_deg_reference` profile flag to `True`.
 
 **Parked, not done:** `DataDrivenLamNI`'s broken `_start_beam_check()` calls
 (missing mixin) — deferred on request, separate task if ever needed.
