The Incus line is a new project, not an upgrade path — remove every
piece of cross-version compatibility:
- version gate: ver.Blocked/MinAdoptable/SemVerLT, blockUnadoptable,
cmdNoteVersion, the installed_version/uninstalled_version config
fields and registry entries, install.sh old-binary detection and the
uninstall note-version call.
- DB migrations for pre-0.3 schemas: migrateAuditTargetDrop,
migrateUserColumns, migrateDomainColumns, migrateCPU and their tests.
- legacy admin-pass migration from config.yaml into the DB.
- duplicate static sudoers file (configs/sudoers.d/vps) — the Go
ensureSudoers embedded copy is the only source.
- docs swept of version-gate and 0.2.x/0.3.x language.
Also rename the bridge lxdbr0 -> incusbr0 across code, scripts, config
and docs, and adapt NIC isolation to Incus 7.0 validation: ipv6_filtering
is only applied when the eth0 device actually carries an IPv6 address or
route (Incus rejects it on a v6-less device, unlike LXD).
