Snowflake: fewer statements per model

Builds issue about a quarter to a third fewer statements, most of them housekeeping that queued for a warehouse behind model work.

  • Models are replaced with CREATE OR REPLACE and no pre-drop. Staging and delta tables are dropped only as the table kind SQLBuild created, and a microbatch delta is kept and replaced between batches.
  • Relation and retention lookups are answered from one SHOW TABLES / SHOW VIEWS listing per schema per run, which needs no warehouse, instead of one information_schema query per table. The run's own DDL invalidates the listing. Session-only statements such as ALTER SESSION SET QUERY_TAG and USE WAREHOUSE keep it.
  • If another session changes the destination just before promotion, promotion reads it again.
  • The fingerprint table is set up once per build. A model whose identity hasn't changed writes no fingerprint row; rows stay append-only. Projects with model migration history keep writing every row.
  • COUNT(*) runs only when a statement reports no row count, and staging columns are read only for models with an enforced contract.
  • Scenario runs list their namespace once by prefix and reuse cleanup results.

Columns read for the schema-change check, and one information_schema read per build for source freshness, are kept.

Compile

  • A compile whose Rules fail writes every model's SQL to target/compiled-failed/, laid out like target/compiled/, with a not-buildable header on failing models, and leaves target/compiled/ as the last passing compile left it. The next passing compile removes the folder. The text report lists each failing model's SQL path; in --json, artifacts.compiled_sql_dir points at the failed folder and failed_model_sql lists the files.
  • target/compiled-models.txt from 0.184.0 is no longer written.
  • The compile after a Rules-failed compile runs in full rather than as a delta.
  • A Rules-failed compile with --manifest no longer reports writing a manifest; JSON artifacts.manifest is null.

Fixes

  • Concurrent models no longer set up the fingerprint table more than once on a first build.
