Adds a -j/--json flag to all buildpacks subcommands (index, info, add, set, remove, clear). Commands that return a buildpack list output the raw BuildpackResponse array; info outputs the registry object; clear and single-removal output an empty array. Updates all unit tests with JSON coverage. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

delete-unused-code (Code style · minor · 60% confidence): The diff adds import {hux} from '@heroku/heroku-cli-util' but hux is never referenced anywhere in this file — run() only delegates to buildpackCommand.clear(...). An unused import is dead code that should be removed rather than left in place.

Code passes - just a note on an import. LGTM!
