fix(cli): improve output consistency and verbose diagnostics

Replace the full help page on no-args with a short usage hint to stderr,
reserving the full help for explicit -h/--help invocations.

Print the active codec skip list at startup under --verbose so
unexpected skips can be diagnosed without resorting to DEBUG mode.

Include the resolved ffmpeg command in dry-run --verbose output, which
is useful for preset authors verifying their ffargs expansion.

Fix the only-if-smaller message to follow the "label: value" convention
used throughout the script.
