Phase 22.1 WIP: SSOT resolver + TLV infrastructure + Hako MIR builder setup

Setup infrastructure for Phase 22.1 (TLV C shim & Resolver SSOT):

Core changes:
- Add nyash_tlv, nyash_c_core, nyash_kernel_min_c crates (opt-in)
- Implement SSOT resolver bridge (src/using/ssot_bridge.rs)
- Add HAKO_USING_SSOT=1 / HAKO_USING_SSOT_HAKO=1 env support
- Add HAKO_TLV_SHIM=1 infrastructure (requires --features tlv-shim)

MIR builder improvements:
- Fix using/alias consistency in Hako MIR builder
- Add hako.mir.builder.internal.{prog_scan,pattern_util} to nyash.toml
- Normalize LLVM extern calls: nyash.console.* → nyash_console_*

Smoke tests:
- Add phase2211 tests (using_ssot_hako_parity_canary_vm.sh)
- Add phase2220, phase2230, phase2231 test structure
- Add phase2100 S3 backend selector tests
- Improve test_runner.sh with quiet/timeout controls

Documentation:
- Add docs/ENV_VARS.md (Phase 22.1 env vars reference)
- Add docs/development/runtime/C_CORE_ABI.md
- Update de-rust-roadmap.md with Phase 22.x details

Tools:
- Add tools/hakorune_emit_mir.sh (Hako-first MIR emission wrapper)
- Add tools/tlv_roundtrip_smoke.sh placeholder
- Improve ny_mir_builder.sh with better backend selection

Known issues (to be fixed):
- Parser infinite loop in static method parameter parsing
- Stage-B output contamination with "RC: 0" (needs NYASH_JSON_ONLY=1)
- phase2211/using_ssot_hako_parity_canary_vm.sh fork bomb (needs recursion guard)

Next steps: Fix parser infinite loop + Stage-B quiet mode for green tests
