Release notes

Added FW_VERSION tracking system with version-history comments. This is the first release where firmware versions are first-class — the boot LED and ACK-payload status both report FW_VERSION so the host can verify what's actually running on each unit.

No functional changes from v5 beyond the version-stamping infrastructure.

Upgrade notes

• Listed here primarily for completeness — recommend going straight to a recent version unless you have a reason to stay back.
