fix(bus,hud): v0.1 S1 cluster — webview didFail + menu-bar icon transition (#40, #41, #151)
#40: BridgeNavigationDelegate gains onDidFail closure (covers didFailProvisionalNavigation + didFail). WebviewBridge.failHandshake(reason:) transitions to new terminal .loadFailed state, cancels pending 2s timeout, fires existing alertPresenter, idempotent. AppDelegate.handleWebviewLoadFailure dual-surfaces: failHandshake + critical non-dismissible banner (defense-in-depth across test seams). WebviewBootHealthProbe gets .loadFailed case.
#41: HudStateCoordinator emit closure now ALSO calls menuBarController.transition(to:) in addition to bridge.send(.hudState(...)). Doc-comment correctly notes this is not a HUD-08 single-writer violation — transition writes currentState, not BusOutbound.hudState. scripts/check-single-writer-hudstate.sh still green.
Tests: 4 new Handshake cases (load-failure-from-sentHello with alert-not-duplicated, from-idle, idempotency, post-armed no-op), BridgeNavigationFailureTests end-to-end + per-arm, MenuBarIconStateTransitionTests drives dormantAgentContinuation and asserts .thinking → .speaking → .idle. 62/62 Bus pass; all 18 boundary gates green.
