test(profiler/behave_shell): H.1 registry-coverage test

Static assertion that every Tier-A primitive in PRIMITIVE_REGISTRY
has a slot in the calibration grid (hard gate or conditional set).
Excludes Tier B (8 cross-session primitives) and Tier C (toolchain.*)
by explicit allow-list and prefix filter.

Three checks:
* every Tier-A primitive is covered (forward direction)
* no extractor set drifts from the registry (reverse, catches typos)
* Tier-A count == 37 (design doc invariant)

CI now fails before a registry addition ships without a feature
function.

+"""Step H.1: registry-coverage test.
+
+Static assertion that every Tier-A primitive in
+``decnet_behave_shell.spec.primitives.PRIMITIVE_REGISTRY`` has a slot
+in the calibration-grid binding sets — either the per-shard hard gate
+(``PHASE_ABCDEFG_PRIMITIVES``) or one of the conditional sets
+(``PHASE_D_CONDITIONAL_PRIMITIVES`` / ``PHASE_F_CONDITIONAL_PRIMITIVES``
+/ ``PHASE_G_CONDITIONAL_PRIMITIVES``).
+
+The test catches a future registry addition that DECNET hasn't
+implemented yet — CI fails before the new primitive can ship without
+a matching feature function.
+
+Tier exclusion (mirrors ``BEHAVE-EXTRACTOR.md:180-223``):
+
+* **Tier B — cross-session, attribution-engine territory:** computed
+  by the attribution engine, never by the per-session extractor. The
+  ``operational.multi_actor_indicators`` primitive is *Tier A* — only
+  its ``team_coordinated`` value is cross-session, not the primitive
+  itself.
+* **Tier C — network domain:** every ``toolchain.*`` primitive is
+  excluded by prefix. Sourced from sniffer / prober / correlation
+  pipelines, not from PTY session extraction.
