 Integration Points
 - Parser EXE → MIR Builder EXE
-  - `./nyash_compiler <in.nyash> | ny_mir_builder --stdin --emit obj -o a.o`
+  - `./nyash_compiler <in.hako> | ny_mir_builder --stdin --emit obj -o a.o`
   - Compose with link step for quick end‑to‑end: `... --emit exe -o a.out`
 - Runner (future option)
   - `NYASH_USE_NY_COMPILER_EXE=1`: Runner spawns parser EXE; optionally chain into MIR Builder EXE for AOT.
