Implemented elegant solution for MapBox as core box with plugin fallback:
1. Core-first Strategy:
- Removed MapBox type_id from nyash_box.toml
- MapBox now uses env.box.new fallback (core implementation)
- Consistent with self-hosting goals
2. Plugin Fallback Option:
- Added NYASH_LLVM_FORCE_PLUGIN_MAP=1 environment variable
- Allows forcing MapBox to plugin path when needed
- Preserves flexibility during transition
3. MIR Type Inference:
- Added MapBox method type inference (size/has/get)
- Ensures proper return type handling
4. Documentation:
- Added core vs plugin box explanation in nyrt
- Clarified the transition strategy
This aligns with Phase 15 goals where basic boxes will eventually
be implemented in Nyash itself for true self-hosting.
