fix(cli): improve --help documentation and add --yes/--check to upgrade

- upgrade: add --yes and --check flags to skip interactive prompt
- benchmark: clarify description — preset fps/quality/worker configs
- browser: describe each subcommand (ensure/path/clear) in help
- docs: list available topics inline in --help output
