Nyash Selfhost Compiler (MVP scaffold)

This is the Phase 15.3 work-in-progress Nyash compiler implemented in Ny.

Layout

• compiler.nyash: entry (CompilerBox). Reads tmp/ny_parser_input.ny, prints JSON v0.
• parser/: lexer/parser/ast (scaffolds; to be filled as we extend Stage‑2)
• mir/: builder/optimizer stubs (future; current target is JSON v0 emit)
• tests/: Stage‑1/2 samples (TBD)

Run (behind flag)

• NYASH_USE_NY_COMPILER=1 target/release/nyash --backend vm <program.nyash>
  • The runner writes the input to tmp/ny_parser_input.ny and invokes this program.
  • It captures a JSON v0 line from stdout and executes it via the JSON bridge.

Notes

• Early MVP emits a minimal JSON v0 (currently a placeholder: return 0). We will gradually wire lexer/parser/emitter.
• Keep JSON v0 spec in docs/reference/ir/json_v0.md.
