refactor(skills/fleet-ops): rename 'fleet fleet' to 'fleet status'

The 'fleet fleet' subcommand stutters with the binary name (reads like
'git git'). Promote 'fleet status' as primary, mirroring 'git status'.

'fleet fleet' remains as a hidden alias for muscle memory; it is no
longer advertised in --help output.

No behaviour change — TUI render is unchanged.
