Overview

The Gemfile Bundler would load from a directory.

Mirrors Bundler::SharedHelpers#find_gemfile: BUNDLE_GEMFILE wins when set and non-empty, otherwise the search walks up looking for gems.rb then Gemfile in each directory. Reimplemented rather than delegated because bundler is deliberately not a gemvault dependency (see gemvault.gemspec) and gemvault doctor runs as a plain CLI, outside any Bundler process.

One difference is deliberate. Bundler returns BUNDLE_GEMFILE whatever it points at, existing or not -- bundler/inline relies on that, setting it to a bare "Gemfile" purely to make Bundler treat the working directory as the app root. The question here is whether bundle install could work, so a value that does not name a file is ignored and the walk-up search decides instead.
