feat(phase73): Stage-3 ENV consolidation complete - Shell scripts

Phase 73-B: Unified legacy Stage-3 environment variables in 27 shell scripts:
- Replaced NYASH_PARSER_STAGE3=1 → NYASH_FEATURES=stage3
- Replaced HAKO_PARSER_STAGE3=1 → NYASH_FEATURES=stage3
- Updated all variant patterns (with/without assignments)

Files modified (27 total):
- tools/dev/*.sh (9 files)
- tools/dev_stageb.sh, dump_stageb_min_mir.sh, hakorune_emit_mir.sh
- tools/joinir_ab_test.sh, ny_selfhost_inline.sh
- tools/perf/*.sh, tools/selfhost/*.sh (9 files)
- tools/hako_check/dot_edges_smoke.sh, tools/selfhost_smoke.sh

Complete Phase 73 consolidation count:
- Phase 73-A: 20 test files + 2 special files (stage3 compat)
- Phase 73-B: 27 shell script files
- Total: 49 files with legacy Stage-3 ENV consolidated

Next: Phase 72 (JoinIR EXPERIMENT SSOT consolidation)
