feat(ring-3): fn signatures → Zig [SEED-3]

[gHashTag]

Closes #6

Summary

• Parse fn parameter lists (name: Type pairs) instead of skipping them
• Add parse_type_annotation() for handling pointer (*T), slice ([]T), array ([N]T), []const T, and anytype types
• Emit full Zig fn signatures with all parameters and return types
• 428 functions across 28 spec files generate correctly (271 with params)

Examples

pub fn trit_add(a: Trit, b: Trit) Trit {
pub fn add_fact(engine: *DatalogEngine, fact: HornClause) bool {
pub fn ternary_word_pack(src: []Trit, count: u8) TernaryWord {
pub fn compose(pattern: CompositionPattern, ml_input: []const f32, ...) CompositionResult {

Testing

• All 28 spec files parse and generate without errors
• Verified simple types, pointer types, slice types, const qualifiers, anytype
• Previous rings (const/enum/struct) unchanged
