- main: the subcommand is a name rather than nil-or-empty argument slices; the cache file and start directory are worked out once; config values with a default go through one valueOr helper. - The link handler's --config argument comes from one configArgs helper. - lazysecrets update parses its flags like the other subcommands, so -check and --check=true work too, and tells a development build by its dev version. - Instance reach is named (unreachable, switchable, inView), tmux client activity is compared as a number, and the best client loop starts from the first. - update: serverTimeout (it bounds the checksums request too), and parentheses in the platform check.
