fix(codegen): VIBEE emits undefined Field type - breaks 2 specs

- Add Field struct definition in codegen_engine_final_upgrade.zig
- Add Field struct definition in codegen_full_automation.zig
- Add eqlPrimitive helper function for string comparison
- Fix StringHashMap usage (takes 1 param, not 2)

Fixes #114
