Move terminal stream buffering, handler fanout, and ack offset state out of DaemonClient into a focused TerminalStreamManager.\n\nReasoning:\n- daemon-client.ts mixed RPC transport concerns with terminal stream state machine details.\n- terminal buffering/ack logic is cohesive and testable in isolation, so splitting it lowers logic density and makes future stream changes safer.\n\nWhat changed:\n- Added daemon-client-terminal-stream-manager.ts to own stream handlers, buffered chunks, and ack monotonicity.\n- Updated DaemonClient to delegate terminal stream state transitions (subscribe, receive chunk, clear stream/all, note ack).\n- Preserved public API by re-exporting TerminalStreamChunk from daemon-client.ts.\n- Hardened daemon-client tests to assert behavior (no delivery/ack after detach or stream_exit) rather than private internal maps.\n- Added dedicated manager unit tests for buffering, eviction, handler-failure behavior, and stale ack suppression.\n\nVerification:\n- npm run test --workspace=@getpaseo/server -- src/client/daemon-client.test.ts src/client/daemon-client-terminal-stream-manager.test.ts\n- npm run typecheck\n\nNext-agent notes:\n- Accomplishment: terminal stream state is now isolated; daemon-client.ts is slimmer and easier to extend.\n- Challenge: daemon-client.ts is still large (~3k lines) with other cohesive seams remaining (dictation flow and checkout RPC groups).
