sic 0.2.1: fix the v2 stdin hang (sicd reaps on child-exit)

sicd + sic-agent -> 0.2.1-1 against sic tag v0.2.1 (tarball sha 0efe5acc…). The daemon fix: it
no longer blocks the stdin pump after the child exits, so sic calls with a never-EOFing stdin
(non-interactive callers holding the pipe open) return promptly instead of hanging to a timeout.
Client unchanged. Pre-flight built (debian amd64 + arch verifysource).
