iomgaa ba4a138692 docs: document the schema mode and the expand-contract promise

README 新增「遥测表 schema 与升级纪律」: 库对下游库只发探测/INSERT/建表
三类语句、PGW_TELEMETRY_SCHEMA_MODE 三态与两端不对称缺省的理由、
telemetry_schema_sql 用法,以及五条 Expand/Contract 承诺。CHANGELOG 未发布段
把三处破坏性变更放在最前。ARCHITECTURE 新增 D15 并在 §7.8/§9 记下 schema
单一事实源与无冲突目标写入。

新增集成用例把 telemetry_schema_sql("postgres") 的输出在空临时 schema 里执行
两遍: 断言物理列 == COLUMNS ∪ {created_at},且第二遍不报错(补列语句的
IF NOT EXISTS 幂等性)。去掉 IF NOT EXISTS 该用例即红。
