Subject: [PATCH] Phase 20.12b: quick green + structural cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Deprecations: add warn-once for nyash.toml (runtime::deprecations); apply in plugin loader v2 (singletons/method_resolver)
- Child env + runner hygiene: unify Stage‑3/quiet/disable-fallback env in test/runner; expand LLVM noise filters
- Docs/branding: prefer  and hako.toml in README.md/README.ja.md and smokes README
- VM: implement Map.clear in MIR interpreter (boxes_map)
- Stage‑B: gate bundle/alias/require smokes behind SMOKES_ENABLE_STAGEB; fix include cwd and resolve() call even for require-only cases
- Core‑Direct: gate rc boundary canary behind SMOKES_ENABLE_CORE_DIRECT
- Smokes: inject Stage‑3 and disable selfhost fallback for LLVM runs; filter using/* logs
- Quick profile: 168/168 PASS locally

This commit accelerates Phase 20.33 (80/20) by stabilizing quick suite, reducing noise, and gating heavy/experimental paths for speed.

 - Using resolution: prefer nyash.toml aliases (SSOT). Some tests may enable `NYASH_ALLOW_USING_FILE=1` internally for convenience.
 - Plugin warnings are informational; smokes are designed to pass without dynamic plugins.
 - Harness single-run may take longer due to link+exec; integration profile includes generous timeouts.
+ - Binary selection in scripts: always use `$NYASH_BIN` (the runner sets it to `target/release/hakorune` when present, otherwise falls back to `nyash`).
+ - Branding: user‑visible messages prefer “Hakorune”; the legacy `nyash` binary remains for compatibility but may be gated（`HAKO_ALLOW_NYASH=1`）。
 
 Dev Mode (defaults)
 - In v2 smokes, the `quick` profile exports `NYASH_DEV=1` by default.
@@ -90,7 +92,7 @@ Common commands
 - Focus JSON smokes:
   - `tools/opbox-json.sh` (Roundtrip/Nested, plugins disabled, generous timeout)
 - One-off program (VM):

+  - `$NYASH_BIN --backend vm --dev apps/APP/main.nyash`
 
 Key env knobs
 - `NYASH_DEV=1` — enable dev defaults (same effect as `--dev`).
