fix(installer): support custom version detection in github_release_binary

Tools like dasel use subcommands (dasel version) instead of flags
(--version) for version output. The default cascade failed because
--version outputs help text and exits 0.

Changes:
- Add version_command support to github_release_binary.sh for custom
  shell commands that extract version numbers
- Add version_flag support for simple subcommand-based version checks
- Add version_command to dasel.json to extract clean version number
- Priority: version_command > version_flag > default cascade
