fix: remove OCaml dune-project and configure Linguist

- Remove dune-project (OCaml build file, not needed for Rust build)
- Configure GitHub Linguist to recognize WokeLang as primary language
- Mark Idris (.idr) and Zig as language sources
- Exclude docs, examples, target from language stats

This fixes GitHub showing 76% Rust + OCaml detection.
Actual stack is: Rust (infrastructure) + Idris2 (ABI) + Zig (FFI) + WokeLang
