nyash-codex 6ecd8f7f52 feat(runtime): Phase 103 CoreServices Optional化 - Memory Constraints対応
- Add CoreServicesConfig struct (from_env, minimal, all_enabled)
- Implement with_core_from_registry_optional() for selective initialization
- Update CoreBoxesImpl fields to Option<Arc<dyn XyzService>>
- Maintain backward compatibility (with_core_from_registry calls all_enabled)
- Add NYASH_CORE_DISABLE_* environment variable support
- ConsoleBox remains mandatory (Graceful Degradation principle)
- Add unit tests for optional initialization
- Update console_println! macro to handle Option type
- Fix direct console.println() calls in vm.rs and selfhost.rs
- Create core_optional_design.md documentation

Note: Phase 104 will extend ConsoleService to be optional as well with
graceful fallback in console_println! macro.

Files modified:
- src/runtime/plugin_host.rs (CoreServicesConfig, with_core_from_registry_optional, tests)
- src/runtime/core_services.rs (CoreBoxesImpl fields → Option type)
- src/runtime/mod.rs (console_println! macro updated)
- src/runner/modes/vm.rs (handle Option console)
- src/runner/selfhost.rs (handle Option console)
- docs/development/current/main/core_optional_design.md (new)
- docs/development/current/main/ring0-inventory.md (Phase 103 entry)

Test results:
- Build:  Success (0 errors, 7 warnings)
- Unit tests:  3/3 passed (optional_core_tests)
- Runtime tests:  63/63 passed
- Smoke tests:  30/31 passed (1 pre-existing timeout)

observe — Builder 観測devonly/既定OFF

目的

  • Builder 内部の決定resolve.try/choose, ssa.phi など)を JSONL で観測する。
  • 環境変数で明示有効化された時のみ動作既定OFF。言語仕様・実行結果は不変。

責務

  • ssa.rs: emit_phi — PHI の決定pred の type/origin、dst の決定)を DebugHub へ emit。
  • resolve.rs: emit_try / emit_choose — メソッド解決の候補/最終選択を emit。

非責務(禁止)

  • MIR 命令の生成/変更は行わない(副作用なし)。
  • 起源付与や型推論は origin 層に限定。

トグルDebugHub 側でガード)

  • NYASH_DEBUG_ENABLE=1
  • NYASH_DEBUG_KINDS=resolve,ssa
  • NYASH_DEBUG_SINK=/path/to/file.jsonl

レイヤールール

  • Allowed: DebugHub emit、Builder の読み取り(関数名/region_id/メタ)。
  • Forbidden: rewrite/origin の機能をここに持ち込まない。
