fix(csharp): escape open enum members colliding with enclosing class name; fix(all): resolve self-recursive additionalProperties maps as value-typed maps

[AshGodfrey]

C#

• Escape open enum members that collide with their enclosing class name, so enums like Tax with a value TAX compile
• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

Python

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

TypeScript

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

Java

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

Go

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

PHP

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

Ruby

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

Terraform

• Generate self-recursive additionalProperties maps as maps of their value type instead of empty models

Summary by cubic

Fixes C# enum member name collisions and corrects self-recursive additionalProperties to generate proper value-typed maps across all SDKs. Prevents compile errors and produces correct map types.

• Bug Fixes

  • C#: Escape open enum members that match the enclosing type name (e.g., Tax/TAX) so code compiles.
  • All SDKs (Python, TypeScript, Java, Go, PHP, Ruby, Terraform): Generate self-recursive additionalProperties as maps of their value type instead of empty models.

• Dependencies

  • Bump github.com/speakeasy-api/openapi-generation/v2 to v2.918.3.

^{Written for commit 0f9b905. Summary will update on new commits.}
