Closes #1040. Bumps claude-code-headless to its merged fix (#61) and wires the app half.

The bug

Press Esc while Claude is streaming and Claude Code closes the HTTP connection. mitmproxy reports that only through its error hook — the stream tap's end-of-stream call, which becomes response-end, runs on a normal end of message. The addon had no error hook, so the adapter never tore the flow down and kept the phase it last published.

What that looked like:

• a pane saying Thinking until the next prompt;
• a goal loop whose turn ended by Esc had no idle edge to resume from — pinned as a known limit in GoalLoopService, because the fix belonged in the package.

The package half (#61, merged)

error(flow) emits response-error — allowed hosts only, flow id and mitmproxy's message and nothing else, because this hook fires for flows that never reached request() and a probe captured a full URL with a query token from a host we do not proxy for. The adapter seals the flow as its stale-flow watchdog would, but immediately: turn stopped, finishTurn with whatever text arrived, phase idle, flow released so a retry drives the UI.

Four review rounds also established:

• a turn that already stopped keeps its phase — a tool message ends cleanly and leaves the pane awaiting-tool while the tool runs locally, and an upstream socket failure says nothing about whether that tool is still running;
• the interruption is neutral: mitmproxy hands the hook Client disconnected. for its own inactivity timeout too (reproduced with tcp_timeout=1), so attributing it to the user would be a guess the UI displays as fact.

The app half (this PR)

ClaudeSession.noteSystemSuspension now tells the adapter the suspension instant immediately, rather than only when the 60 s seal grace expires (#963). A sleep-severed stream usually reports its own death first — a transport error seconds after wake — and whichever signal arrives first decides what the user is told. Without this the turn was reported as a transport failure, the later seal found no flow left to attribute, and the shared desktop/phone ledger lost "Interrupted while asleep."

Tests

• Package: ClaudeProxyAdapter.clientDisconnect.test.ts (7 cases) and mitmAddon.error.test.ts, which runs the Python hook itself against a stub mitmproxy and asserts both the payload shape and the silence for a non-allowed host.
• App: claudeSession.suspension.test.ts — the adapter is told before the grace, and a session with no proxy still works. Fails without the call.

tsc -b clean.
