fix(stage-b): Add sh_core using + Stage-1 JSON support
## Fixed Issues
1. compiler_stageb.hako: Added 'using sh_core as StringHelpers'
- Resolved: call unresolved ParserStringUtilsBox.skip_ws/2
- Root cause: using chain resolution not implemented
- Workaround: explicit using in parent file
2. stageb_helpers.sh: Accept Stage-1 JSON format
- Modified awk pattern to accept both formats:
- MIR JSON v0: "version":0, "kind":"Program"
- Stage-1 JSON: "type":"Program"
## Remaining Issues
ParserBox VM crash: Invalid value: use of undefined value ValueId(5839)
- Cause: Complex nested loops in parse_program2()
- Workaround: Minimal Stage-B (without ParserBox) works
- Fallback: Rust compiler path available
## Verification
✅ Minimal Stage-B outputs JSON correctly
❌ ParserBox execution crashes VM (SSA bug)
