Two bugs in agent-smoke.sh caused non-deterministic CI failures:

1. SIGPIPE race with pipefail: `printf | grep -q` fails when grep closes
   the pipe early after finding a match, causing printf to get SIGPIPE
   (exit 141). With pipefail, the pipeline returns non-zero even though
   grep succeeded — producing false "undef" failures. Fixed by using
   here-strings (<<<) instead of pipes for all grep checks.

2. Incomplete LIB_FUNS: hand-maintained REQUIRED_LIBS list (11 files)
   didn't cover all 26 lib/*.sh files, silently producing a partial
   function list. Fixed by enumerating all lib/*.sh in stable
   lexicographic order (LC_ALL=C sort), excluding only standalone
   scripts (ci-debug.sh, parse-deps.sh).
