research(track-a): census native action control boundaries

Researcher source for OTC-20260818-track-a-s9-action-control-static-census.

Coordinator accepted/promoted via PR #537, squash merge ebbb36f50076ff4072c7218e302614c1dfea00b1.

Canonical result:

retained *GameActionHandler QMeta denominator = 28
movement/path/rotate/stop/cancel native boundaries = proven QMeta
attack/follow/look boundaries = proven QMeta
use/use-with/use-on-creature boundaries = proven QMeta
move-object/equip/container boundaries = proven QMeta
chat/NPC/player/internal-router boundaries = proven QMeta

Retained causal limit:

action layer -> exact protocol connection = UNKNOWN
per-action protocol -> serialized message = UNKNOWN
per-action runtime/server effect = NOT_OBSERVED
static action/control catalogue = EXHAUSTED_FOR_RETAINED_QMETA

This closes the independent repo-only S1-S9 static wave. Further meaningful proof requires approved exact-build code/disassembly windows or a later legal non-conflicting runtime surface. Repeating QMeta/name scans is no longer useful.
