Ruby extraction honesty (Tier 1)

FQN conventions:

• Nested constants: Module::Class
• Instance methods: Module::Class#method
• Class/singleton methods: Module::Class.method
• Constructors: Module::Class.<init> with metadata.is_constructor: true

Limits (static analysis only):

• No $LOAD_PATH, Bundler, or Zeitwerk resolution for require
• No Ruby method lookup, super target resolution, or refinements algebra
• Dynamic send / method_missing → Calls with metadata.unresolved
• include / prepend modeled as mixin Extends; extend as Uses
• Block/yield CFG uses nested sub-CFGs; yield edges are conservative
• Chef/Rails magic deferred to follow-up plugins
