[GH-7316] Prepare Rubyzen for public release

[Copilot]

Pull request overview

This PR prepares Rubyzen for a public gem release by formalizing packaging (gemspec/Gemfile), simplifying configuration via auto-discovery, and renaming custom RSpec matchers to avoid collisions with built-in RSpec matchers.

Changes:

• Introduces rubyzen.gemspec + lib/rubyzen/version.rb, and switches Gemfile to gemspec.
• Replaces env-var-based configuration with Rubyzen.configure { |c| c.paths = ... } plus auto-discovery of app/ lib/ src/ spec/.
• Renames matchers to zen_empty, zen_true, zen_false and removes the previous expect override + deprecated matcher.

• Same portability/flakiness concern as above: the array includes a hard-coded /non/existent/path. Prefer a generated non-existent temp path so the spec is deterministic across environments.
