Release 0.2.0: dhcpsrv lease auto-discovery, SDS MAC pairing, preflight, flat archive

- Auto-pick BMCs from the dhcpsrv lease table; resolve SDS by neighbouring MAC
- Preflight host-state table (power/work, BMC/UEFI/FPGA) before collection
- Single flat tar.gz bundle (no nested per-host archives); auto-open output dir
- BMC default creds admin/V36man; SDS commands run as root; clearer SSH error hints
- Pin paramiko<4 (5.x dropped ssh-rsa host keys that YADRO BMCs require)
- Timestamped crash reports under crashlogs/

dev/pyproject.toml
