feat: add functional CodeBlock system for code generation#67
Conversation
Introduce a React-like approach where handlers return code blocks instead of imperatively mutating a CodeBuilder. - Add CodeBlock class with automatic indentation handling - Add `code` tagged template for composing blocks - Add helper functions: ifBlock, ifElseBlock, forBlock, compose - Create type-functional.ts as proof of concept This enables cleaner, more testable code generation where each handler is a pure function returning its generated code.
Remove helper functions (ifBlock, forBlock, etc.) - the `code` template literal is sufficient for all patterns. Just write the code you want to generate. Also update type-functional.ts to use pure `code` templates with inline if statements instead of helpers.

Instead of manually writing if/error blocks:
code`if (!(${check})) { ${genError(...)} }`
Use the fail.unless primitive:
fail.unless(check, ctx, 'keyword', 'message', params)
Takes the PASSING condition and negates internally,
avoiding operator precedence bugs with manual negation.
