fix(daemon): support chunked IPC responses to avoid pipe truncation

[haosenwang1018]

Summary

• fix daemon client IPC response parsing to handle chunked socket data correctly
• accumulate incoming bytes until newline-delimited JSON frame is complete
• avoid parsing partial frames (which can silently cut large payloads)
• make timeout/error handling single-settle safe to avoid duplicate resolve/reject races

Why

Issue #23 reports output truncation at exactly 65536 bytes when piping. The daemon IPC client currently parses each socket data event as if it were a complete JSON response. On large responses, data may arrive in multiple chunks, causing partial-frame parsing and truncated downstream output.

This patch aligns the client with daemon framing (JSON lines) and only parses after a full frame is received.

Closes #23
