Debug command and subcommands not visible in --help output

[assagman]

Description

The debug command and all its subcommands are not visible in --help output because they are missing the describe property in yargs command definitions.

Running opencode --help does not list the debug command, and running opencode debug without arguments shows an error instead of listing available subcommands.
