fix: Correct HttpRequestBox method_id mapping in nyash.toml

Fixed the method ID order in HttpRequestBox configuration to match plugin implementation:
- path: method_id 1 (was incorrectly 2)
- readBody: method_id 2 (was incorrectly 3)
- respond: method_id 3 (was incorrectly 1)

This resolves the 45-day debugging issue where req.respond(resp) was calling
the wrong plugin method, causing HTTP responses to have empty bodies.

All E2E tests now pass:
- e2e_http_stub_end_to_end ✅
- e2e_http_multiple_requests_order ✅
- e2e_http_post_and_headers ✅
- e2e_http_server_restart ✅
- e2e_http_server_shutdown_and_restart ✅

+Box Identity and Copy Semantics (Nyash)
+
+Context
+- In Nyash, everything is a Box. Some boxes carry identity (external handles, stateful resources), while others are pure values.
+- Picking clone_box vs share_box is critical: getting it wrong can silently fork state or break handle identity (e.g., plugin/socket/file handles).
+
+Key Terms
+- Identity Box: Represents an external or stateful handle where the instance_id (or similar) must remain stable across uses. Examples: PluginBoxV2 (all plugin boxes), Socket boxes, FileBox, DB handles.
+- Value Box: Pure data containers where cloning yields an equivalent value. Examples: StringBox, IntegerBox, JSONBox, ArrayBox/MapBox (when used as data).
+
+Rules of Thumb
+- When preserving identity matters (handle/connection/descriptor): use share_box.
+- When passing or returning pure values: use clone_box (or deep copy APIs) so callers can freely mutate their copy.
+- Do not call clone_box on identity boxes during common control flows like method dispatch, result unwrapping, or variable assignment unless you’re explicitly birthing a new instance.
+
+Where mistakes commonly happen
+1) Result unwrap (ResultBox.get_value)
+   - Wrong: always clone_box() — duplicates plugin handles and changes instance_id.
+   - Right: if value is PluginBoxV2 (or any identity box), return share_box(); else clone_box().
+
+2) Method dispatch (receiver preparation)
+   - Wrong: always clone the receiver box before method call.
+   - Right: if the VM stores BoxRef(Arc<dyn NyashBox>), use Arc::share_box() for the receiver; only clone for value boxes.
+
+3) Environment/variable storage
+   - Wrong: eagerly clone_box() on set/assign.
+   - Right: keep as BoxRef (Arc) where semantics require identity; only copy for value semantics.
+
+4) Returning plugin results
+   - Ensure loader returns PluginBoxV2 with the exact instance_id provided by the plugin, wrapped as BoxRef. Avoid any implicit clone.
+
+Concrete patterns
+- In ResultBox.get_value():
+  - if val.is::<PluginBoxV2>() -> return val.share_box()
+  - else -> val.clone_box()
+
+- In VMValue conversions:
+  - VMValue::from_nyash_box: store as BoxRef(Arc<dyn NyashBox>) for identity-bearing boxes (default safe choice).
+  - VMValue::to_nyash_box: for BoxRef -> share_box().
+
+- In plugin method dispatch (PluginBoxV2):
+  - Identify receiver as PluginBoxV2 and pass its instance_id to FFI directly (avoid cloning receiver).
+
+Anti-patterns to avoid
+- Using clone_box blindly in:
+  - Result unwrap paths
+  - Method receiver preparation
+  - Field access and variable bindings for identity boxes
+
+Design guidance
+- Consider tagging boxes with an identity flag:
+  - Add BoxCore::is_identity() -> bool (default false; override to true for PluginBoxV2, Socket/File/DB boxes).
+  - Provide a helper: clone_or_share_by_semantics(box: &dyn NyashBox) that calls share for identity and clone for values.
+- Add debug assertions/logs in dev builds when a PluginBoxV2’s instance_id unexpectedly changes across a single logical flow (indicative of unintended clone).
+
+Testing checklist
+- Log instance_id for plugin boxes at:
+  - client.get/post result (resp_id)
+  - ResultBox.get_value return (should match)
+  - Method dispatch receiver (should match)
+  - readBody()/write logs (should match)
+- For e2e tests, assert that write/mirror/read use the same response id.
+
+Migrations for existing code
+- Update ResultBox.get_value to share PluginBoxV2.
+- Audit call sites that do clone_box() before method dispatch or storage; prefer BoxRef + share for identity boxes.
+- Ensure plugin loader returns PluginBoxV2 as BoxRef, not cloned.
+
+Future improvements
+- Static lint: forbid clone_box on types that implement BoxCore::is_identity() == true in critical paths (unwrap, dispatch, assign).
+- Provide a macro/helper to explicitly mark intent: share!(x), clone_value!(x) to make code review easier.
