Follow-up fix added after live validation. /compact was lowering OpenCode's local context correctly, but the next normal request resumed the old sticky Claude session, whose hidden pre-compaction context reported ~806k cached input tokens. b4d999 adds the regression; 858a34 clears the base conversation binding at a classified summary boundary so the next turn transfers compacted OpenCode history into a fresh Claude session. Focused regressions, typecheck, build, and diagnostics pass. The full suite still stops at the unchanged Windows smoke assertion in test/smoke.ts:236. |

Introduce ClaudePromptInput, a long-lived AsyncIterable<SDKUserMessage> backed by an unbounded queue. Each push() resolves the next pending pull; close() releases any waiting consumer. This is the primitive the proxy uses to stream user input into a persistent Agent SDK Query.

Closing the prompt input tears the SDK stream down synchronously. Doing it inline meant every turn paid to close the previous turn's bridge before it could proceed, adding seconds to every request. Measured on Windows with Opus 5: ~11s for a trivial prompt, ~3s once deferred. The close still happens, so the stream leak this branch fixes stays fixed — it just runs on the next macrotask instead of while a request is waiting. handle.close() and removal from the pool remain synchronous. Adds test/bridge-teardown-regression.ts covering both teardown paths: deleteBridge, and putBridge superseding an earlier turn for the same conversation.
