Subject: [PATCH] feat: default to 'show' subcommand when jjf is invoked
 without args
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the original bash+fzf script's behavior — `jjf` alone becomes
a quick rev browser. Implemented in shell wrappers (so the --emit
history-rewrite path still applies); the binary itself still prints
usage on bare invocation, for explicit invocations.
