v0.26.6: bump version

A caller that resolves Unit Keys out-of-band can now set disable_keydb
so the scan consults no keydb at all — neither an explicit keydb_path
nor the standard search locations. Without it, a keydb that merely sits
in a default location ('~/.config/...') silently shadows the out-of-band
path. unit_key still takes precedence over everything.
