Q-W4: split actions.cpp into design_view_actions/bank_actions/prune_action + shared action_registry; bank verbs deduped into promptless bankOp* inner verbs in panel_bank_ops (one mutation home, two UX skins); command-id strings byte-identical; actions.h shim carrier retired

+// bank_actions — the multi-bank bindable action family (Phase B3; Q-W4 split of
+// actions.h). The bindable action set that drives the multi-bank workflow: create /
+// rename / delete / evacuate a bank, activate a bank (direct pool + cycle), move /
+// copy / remove the panel's selected samples, the two vertical-split full-height
+// toggles, and the Phase R prune action's registration + dispatch (its guarded body
+// lives in prune_action). Q-W4 dedupe: every mutating handler here is a THIN UX skin
+// (text prompts + console messages) over the promptless bankOp* verbs homed in
+// panel_bank_ops — one implementation home for each mutation, two UX skins (this
+// family prompts for which bank; the panel acts on a clicked tab).
+//
+// Same registration/routing/unload contract as the Design View family
+// (design_view_actions); both share main.cpp's single hookcommand, and each family's
+// Handle claims only its own ids. This header is SDK-free.
+
+// Forward-declared at GLOBAL scope (matches reaper_plugin.h's typedef) so this
+// header stays SDK-free; the .cpp includes the real definition.
