nyash-codex b21ee3c854 fix(parser): Part 3-4 - Fix remaining infinite loops in parser subsystems
Part 3 (included):
- parser_box.hako: Fix semicolon consumption loop (lines 401-421)

Part 4 (systematic fix of 7 files):
- parser_number_scan_box.hako: Fix scan_int digit scanning loop
- parser_literal_box.hako: Fix parse_map and parse_array loops (2 loops)
- parser_peek_box.hako: Fix peek expression arms parsing loop
- parser_control_box.hako: Fix parse_block and semicolon loops (2 loops)
- parser_exception_box.hako: Fix try/catch clauses loop
- parser_stmt_box.hako: Fix using statement namespace parsing loop

Root cause: MirBuilder bug with loop(flag == 0/1) + nested if-else
- Generated broken MIR with PHI self-references
- Caused infinite loops in VM execution

Solution: Convert all problematic loops to MirBuilder-friendly pattern:
  loop(true) { if condition { continue } else { break } }

Test results:  Stage-1 CLI now completes without timeout
- Exit code: 0
- MIR dump created successfully
- parse_program2 ws_init: 1 iteration (was infinite)

Total loops fixed across all parts: 18 loops in 11 files

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.
  • FailFast: 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

NonGoals

  • 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)
  • PolicyPhase 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 EXEhakorune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。
