nyash-codex c5abf62350 docs(phase84): Add Phase 84-3 analysis and Phase 84-4 recommendations ...

Task agent investigation results after Phase 84-3 completion.

Remaining 4 Case D analysis:
- test_lowering_await_expression: await construct
- mir_lowering_of_qmark_propagate: QMark (?) construct
- mir_stage1_cli_emit_program_min_*: Stage1Cli type inference (2 tests)

Root cause (unified): BoxCall/Await/QMark return types not registered in value_types

Phase 84-4 implementation recommendations:
- Phase 84-4-A: dev fallback (0.5 days) - immediate unblock
- Phase 84-4-B: BoxCall type registration (1-2 days) - solves 3 cases
- Phase 84-4-C: Await type special handling (0.5 days) - solves 1 case

Documents added:
- phase84-3-summary.md: Reduction results and Phase 84-4 recommendations
- phase84-3-remaining-4-analysis.md: Detailed analysis of each test
- phase84-4-implementation-recommendation.md: Implementation guide with code examples
- phase84-index.md: Phase 84 overall index and roadmap
- phase84-3-final-report.md: Complete report with executive summary

Cumulative results:
- Phase 82: 12 cases
- Phase 84-2: 9 cases (25% reduction)
- Phase 84-3: 4 cases (56% reduction)
- Total: 67% reduction achieved (12 → 4)
