iamroot-fleet-scan.sh — bash wrapper that scp's the iamroot binary
to a host list, ssh-runs --scan --json on each, aggregates results
into a single JSON document. Supports:
- hosts list from file or stdin
- user@host:port syntax
- parallel xargs execution (default -P 4)
- ssh key / extra ssh opts pass-through
- --no-sudo for hosts where root isn't required
- --summary-only to suppress per-host detail
- --no-cleanup to leave the binary on disk

Critical fix during smoke-test: iamroot's exit codes are SEMANTIC
(0=OK, 2=VULNERABLE, 4=PRECOND_FAIL, 5=EXPLOIT_OK). The wrapper
must NOT treat nonzero exit as a transport failure; success is
defined by 'stdout contains valid JSON', failure by 'stdout empty'.

Verified end-to-end on kctf-mgr → kctf-fuzz:
  fleet-scan reports ok=1, failed=0,
  summary.vulnerable groups by CVE: copy_fail_gcm, dirty_frag_esp×2,
  entrybleed. Per-host detail included.
