Converged scope: supplemental tests stacked on #167

Refs #157 #83 #85. Current head b0ec3fc, tree 765b569ba3508019eda1cf85161a335ffcea508f.

To avoid two competing storage implementations, this PR now adopts #167 source a85b744 unchanged and adds only the existing 16 independent backend-parity tests, their focused cloud workflow, and docs/METADATA_SESSION_PROGRESS.md. It is retargeted to #167's branch. The old and adopted histories are preserved by a non-force two-parent commit.

The tests retain all assertions. Only four references to the neutral base name are aligned to #167's canonical RelationalSession. The adopted implementation supplies the explicit QuerySession/QueryResult port, transaction-lifetime result guards and missing declared domain methods; this is not a second base, query wrapper or database service. No upstream branch or main was overwritten.

Preserved evidence (old source, not new-head certification)

• Red 36481798533, exact7f8752e / tree686dbdd: 4 failed, 12 passed, 0 errors/skips; all failures were new architecture assertions.
• Original exact implementation0ef416ec / treead1d3f4: focused 36483460243 16 new +80 existing =96 passed, 0 failures/errors/skips. Both JUnit/source files read; artifact10997317418 SHA256 verified 8a9cc70e9c31d19baf18050f42eda11818786d671863ded05d35b5e9ab098354.
• The original 42-method/Store/schema/driver AST audit and source hashes remain in the progress note; its parallel implementation is superseded, not separately merged.

Current gate

The new combined source must pass focused, complete four-shard exact node-ID, conformance/build and Recovery safety again. No green result is yet claimed for b0ec3fc. #167 and #169 also overlap on the executor and must converge before main integration; #165 has already moved main to08c58928. Do not treat old-head or parent passes as combined-head evidence.

Tests cover independent PostgreSQL import, neutral ownership, actual declared contract, both database adapters' resource versions/path/paging, result/event/audit/job identities, rollback/savepoints, read-only/closed/cross-task guards, constraint rollback and SQL literals. Existing PostgreSQL lock/concurrency, ledger migration and recovery regressions remain.

No production, Root/PIN, real funds/outbound effects, schema migration, backup destruction or restore promotion. Umbrella/production-evidence issues stay open.

已对照本PR源码与tests/test_metadata_session_boundary.py。与 #167 的 #157 实现重复，建议收敛为一个存储基类，不串行引入 MetadataSessionBase/RelationalSession 两套定义。

本PR的12个双后端行为回归覆盖资源代际/路径/分页、result/event/audit/job、补偿范围、只读/跨任务/关闭、冲突回滚、占位符，均有独立价值；本会话将保留这些行为断言到#167的组合验收。四个结构断言也将按唯一最终类型保留，不通过删除断言掩盖回归。

#157追加评论要求的实际查询接口缺口不能把one/rows/path/job等称为storage-local就忽略：market.policy等真实消费者仍调用。#167同时补QuerySession、五个域方法声明和受会话生命周期约束的查询结果。当前a85b744/tree042422的存储专项36483874055已success，完整结果尚待验证。

不改写本PR源分支，保留原red/assembly证据；待合并唯一实现并完成组合回归后再关闭重复PR，不现在宣称#157全验收完成。
