* feat(#1680): ADR-1239 Phase C-1 — hook-bus + stateIO seams [AC4] Phase 3 slice 4 (AC4, final #1680 slice). The last two adapter seams behind the negotiated hookBus/stateIO axes: - src/hook-bus.cts: createHookBus({bus}, {hostEmit?}) -> host/engine/none. engine = in-process pub/sub (handler errors isolated); host = host-owned, fail-closed emit until a host emitter is bound; none = silent no-op (degrade to rule-text). PORTABLE_EVENT_FLOOR = SessionStart/PreToolUse/PostToolUse/ Stop/SessionEnd (the claude dialect all hook hosts share). - src/state-io.cts: createStateIO({io}, {backend?}) -> filesystem (today's behavior — straight fs) / sandboxed-storage / session-log-append (fail-closed seams until a host backend is bound). Proactive CI gates: ADR-457 ignores + INVENTORY-MANIFEST entries for both new .cjs; injection-scan 'act as' substring audit; unused-import check. All clean locally (11 tests + security 15/15 + inventory + eslint 0 problems). Phase 3 (#1680) seam layer now complete. Concrete host binding -> Phase 5 (#1682, D15/D18). * chore(changeset): add Changed fragment for hook-bus + stateIO seams (#1680)

Internal: hook-bus + stateIO adapter seams — createHookBus({bus}) (new src/hook-bus.cts, host/engine/none — engine is in-process pub/sub, host fail-closed, none silent) + createStateIO({io}) (new src/state-io.cts, filesystem/sandboxed-storage/session-log-append — filesystem delegates to fs, the rest are fail-closed seams) (ADR-1239 Phase C-1 / #1680 AC4). Completes the Phase 3 adapter seam layer; concrete host binding is Phase 5. No user-facing change.
