v0.6.1

Fixed

• Node.js package publishing: Fixed @spikard/node package.json to correctly publish the TypeScript wrapper layer (Spikard class, routing decorators, type-safe utilities) that was missing from v0.6.0, which only contained low-level FFI bindings
• Ruby gem publishing workflow: Fixed bash exit handling in RubyGems version check script to prevent premature workflow failures when gem version doesn't exist
