v0.3.0 — subcommand-aware flags & bare flag clusters

Accuracy pass driven by real commands people try.

Fixes

• docker build -t now correctly reads as tag (was showing tty); the image name is labelled as its value.
• kubectl logs -f now correctly reads as follow (was showing file); the pod name is no longer swallowed as the flag's value.
• Traditional no-dash flag clusters like tar czf … and ps aux now expand per-letter instead of being shown as one opaque argument.

Internals

• New subFlags / subTakesValue / bareFlags fields in the command DB for per-subcommand flag meanings.
• 3 new regression tests (15/15 passing).
