Q-W6: registration table (OCP) in main.cpp; bank verbs -> shell/bank_ops(Session&); persist.h + wav_trim + namespaces.h shims deleted; 61/61

capture.h realtime seam split to capture_realtime_shell.h; GetProjExtState grow-loop rehomed to core/wire/ext_state_read; stale persist.cpp/bank_panel.cpp comment refs fixed; CLAUDE.md persist/bank_book/actions bullets updated. Command-id suffixes, display phrases, and undo labels byte-identical.
