Prove planner validation commands execute without manual reconstruction

Constraint: Adding validation_commands to the planner was only useful if the emitted commands could be consumed directly, so the plan artifact needed one more layer of execution proof.
Rejected: Assume command strings are correct because they look valid | That would leave restart automation unproven.
Confidence: high
Scope-risk: narrow
Directive: Prefer executing validation_commands from the planner artifact instead of retyping equivalent checks by hand.
Tested: git diff --check; /usr/local/miniconda3/bin/python - <<'PY' ... execute validation_commands.prereq_audit and validation_commands.worker_contract_smoke from data/pgvector_eval/music20/phase1_extraction_plan_report.json ... PY
Not-tested: The remaining planner validation commands were not executed in this commit, though their sibling commands proved the artifact is directly consumable.

+- 新增 `phase1_validation_commands_execution_report.json`，直接从 `phase1_extraction_plan_report.json` 读取并执行 `validation_commands.prereq_audit` 与 `validation_commands.worker_contract_smoke`，两条命令均返回 `0`，证明 planner 产物可被脚本化直接消费。
 - 更新 `scripts/plan_phase1_extraction_jobs_live.py` 与 `phase1_extraction_plan_report.json`，除了 per-job `command_suggestions` 之外，又补充了 `validation_commands`：`prereq_audit`、`worker_contract_smoke`、`semantic_vector_negative_matrix`、`asset_level_upsert_validation`，使 planner 本身也成为下次 session 的执行入口。
 - 新增 `scripts/run_phase1_prereq_audit_live.py` 与 `phase1_prereq_audit_report.json`，把 `/workspace/downloads` 挂载状态、`torch/torchaudio/transformers/speechbrain` 依赖状态与 5 条 Phase-1 jobs 的 readiness 汇总到一份 live 审计报告；当前结果为 `ready_jobs=0`、`blocked_jobs=5`。
 - 新增 `scripts/run_embedding_vector_table_negative_matrix_live.py` 与 `embedding_vector_table_negative_matrix_report.json`，在 live PostgreSQL 上补齐 semantic preflight 的三类向量表负例：维度不匹配、未 allowlist、schema 缺表；三类 case 都会稳定落到 `preflight_failed`，且 `vector_table_report.reason` 与预期一致。

+- `acr-engine/data/pgvector_eval/music20/phase1_validation_commands_execution_report.json`
+
+当前已验证：
+
+- `validation_commands.prereq_audit` -> `returncode = 0`
+- `validation_commands.worker_contract_smoke` -> `returncode = 0`
+
+这说明 planner 报告现在不仅能“展示命令”，还可以被脚本化消费为真正的执行入口。
