nyash-codex 844e53d96c fix(parser): Part 5 - eliminate infinite loops in parse_string2 and scan_with_quote 
Problem: Nested escape sequence processing in string parsing functions caused
infinite loops due to missing continue statements, allowing fallthrough to the
else block which corrupted the position counter.

Fixed functions:
- parser_expr_box.hako::parse_string2 (lines 22-83)
- parser_string_scan_box.hako::scan_with_quote (lines 11-101)

Changes:
- Flattened nested 'else { if ... }' chains to flat 'if' statements
- Added explicit 'continue' after each escape sequence processing
- Prevents fallthrough to position increment code

Verification:
✅ NYASH_USE_STAGE1_CLI=1 STAGE1_EMIT_PROGRAM_JSON=1 HAKO_VM_MAX_STEPS=2000000
   apps/tests/minimal_ssa_skip_ws.hako
✅ No budget exceeded
✅ Program JSON v0 output to stdout
✅ Exit code: 0

MirBuilder-friendly pattern applied consistently with Parts 1-4.
Stage-1 CLI infinite loop elimination COMPLETE!

Hakorune Lang Line — Rust-less Kernel (C ABI)

Scope

  • This lang/ tree hosts the script-driven C ABI kernel artifacts for Phase 20.9+.
  • Goal: keep the runtime data plane callable without Rust on the hot path (Hakorune → LLVM → C ABI).

Principles

  • Separation: do not mix Rust crates or cargo-specific layout under this tree.
  • Ownership & ABI:
    • Any char* returned across the ABI is owned by the callee and must be freed via hako_mem_free().
    • Do not mix CRT free() across boundaries.
  • Fail‑Fast: no silent fallbacks. Missing symbols must be observable via short diagnostics.

Layout (initial)

  • c-abi/ — C shim(s) and headers for the minimal kernel surface
    • README.md — responsibilities, build notes, platform caveats
    • include/ — public headers (mirrored or thin wrappers)
    • shims/ — libc-backed shim(s) for canaries and local testing

Build & Link (dev)

  • C shim: build a shared library to satisfy symbols for the LLVM line canaries.
  • Link flags example:
    • Linux: -L$(pwd)/target/release -Wl,-rpath,$(pwd)/target/release -lhako_kernel_shim

Non‑Goals

  • Plugin loader, HostBridge router, Box/Type system — kept in Rust.

Selfhost Launcher (AOT)

Dev line (Stage1 core – experimental)

  • Dev build: tools/selfhost/build_stage1.sh → produces target/selfhost/hakorune
  • Role:
    • Fast iteration用の Stage1 selfhost バイナリ（Ny Executor / CLI 実験など）。
    • new CLI/runner 機能はまずこちらで開発・検証する。

Stable line (lang bin – snapshot)

  • Stable binary: lang/bin/hakorune
  • Build (pure-lang launcher, legacy bring-up):
    • lang/build/build_runner.sh → produces lang/bin/hakorune
    • Requirements: LLVM 18 dev (llvm-config-18)
  • Policy（Phase 25.1 以降の想定）:
    • target/selfhost/hakorune で十分に安定したら、その成果物を lang/bin/hakorune に昇格させる（手動コピー or 専用スクリプト）。
    • lang/bin/hakorune は「last known good」の Stage1 コア EXE として扱い、配布や外部からの参照時は原則こちらを基準にする。

Notes

  • lang/ 以下は「最終的に 1 つの Stage1 コア EXE（hakorune）を構成するソース群」という前提で整理する。
  • target/selfhost/hakorune は開発中の最新版、lang/bin/hakorune は安定版スナップショットという役割分担にする。
