feat: add MLIR and TableGen language support

Adds tree-sitter-based parsing for:
- MLIR (.mlir) — 47/48 files parse clean on ascendnpu-ir
- TableGen (.td) — 50/50 files parse clean

WASM grammars are built from:
- artagnon/tree-sitter-mlir (latest GitHub, ABI v15)
- Flakebi/tree-sitter-tablegen (v0.0.1)
