refactor(llvm): Complete Resolver pattern implementation across all instructions

Browse Source 
Major structural improvement driven by ChatGPT 5 Pro analysis:
- Replace all direct vmap access with Resolver API calls
- Add proper cursor/bb_map/preds/block_end_values to all instruction handlers
- Ensure dominance safety by localizing values through Resolver
- Fix parameter passing in invoke/fields/extern handlers

Key changes:
- boxcall: Use resolver.resolve_i64/ptr instead of direct vmap access
- strings: Remove unused recv_v parameter, use Resolver throughout
- invoke: Add missing context parameters for proper PHI handling
- fields: Add resolver and block context parameters
- flow/arith/maps: Consistent Resolver usage pattern

This addresses the "structural invariant" requirements:
1. All value fetching goes through Resolver (no direct vmap.get)
2. Localization happens at BB boundaries via Resolver
3. Better preparation for PHI-only-in-dispatch pattern

Next: Consider boxing excessive parameters (15+ args in some functions)
