fix(selfhost): propagate Stage-3 parser flags to child processes

Browse Source 
Phase 25.1b selfhost builder stabilization - prevent "Undefined variable: local" in nested compilations

Changes:
- src/runner/child_env.rs:
  - Add Stage-3 parser flag propagation in apply_core_wrapper_env()
  - Propagate NYASH_PARSER_STAGE3, HAKO_PARSER_STAGE3, NYASH_PARSER_ALLOW_SEMICOLON
  - Ensures child processes (inline compiler, using resolution) support 'local' keyword

Context:
- When selfhost builder uses `using` to load modules, inline compiler spawns child processes
- Without this fix, child processes don't inherit Stage-3 flags → "Undefined variable: local"
- Part of HAKO_SELFHOST_BUILDER_FIRST=1 (no fallback) selfhosting strategy

Note: This is partial fix - inline compiler still needs forced Stage-3 mode (next commit)
