fix: fully qualify type references in generated expressions

[ycherkes]

Summary

• Qualify static member references with global:: in generated expressions.
• Qualify additional type-bearing syntax, including:
  • as expressions
  • generic type arguments
  • declaration and recursive patterns
  • explicit array creation
  • sizeof(...)
  • enum/static member access
• Expand regression coverage for collision-prone type references.
• Bump AlephMapper from 0.7.3 to 0.7.4.
• Refresh generated-source fixture version stamps
