Bootstrap missing tables for incremental materializations

[albertobruin]

What

Incremental merge, delete+insert, and time_interval materializations now create an empty target from the asset query schema when the target does not exist.

Changes

• Shared empty-CTAS helper plus dialect-specific implementations across supported SQL platforms
• Athena catalog check and hook-aware initialization, Oracle dynamic PL/SQL, and Redshift LIKE staging
• BigQuery bootstrap tables preserve partitioning, clustering, require_partition_filter, and partition_expiration_days
• Cross-platform regression tests and materialization documentation

How to test

1. make format
2. make test
3. make build-no-duckdb

Risk & rollback

• Risk: Medium — generated SQL changes across many warehouse dialects, with unit coverage but no live warehouse integration run.
• Rollback: Revert the merge commit.

Checklist

• Unit tests added or updated (make test)
• Builds and lint pass (make build-no-duckdb, make format)
• Integration tests pass if affected (make integration-test)
• No unrelated changes included
• Tested locally

Security

• No secrets, credentials, or PII in this change
• No new dependencies with known vulnerabilities
• Security implications considered

### Issue 1
pkg/clickhouse/materialization.go:83-88
**Bootstrap drops ClickHouse partitioning**

When a `delete+insert`, `merge`, or `time_interval` asset with `partition_by` runs before its target exists, the bootstrap DDL creates the table without the configured partition key. Since subsequent runs skip `CREATE TABLE IF NOT EXISTS`, the target remains permanently unpartitioned until it is manually rebuilt.

This is going to be nice, thank you!
