Why

SQLBuild still depended on a temporary Polyglot fork even though active upstream releases are available. Upstream 0.11.0 also retains one Snowflake parser gap for a dynamic bracket expression applied after a VARIANT path.

Changes

• replace polyglot-sql-chio 0.9.3 with upstream polyglot-sql 0.11.0
• keep parser and SQL-test cache identities tied to the installed upstream distribution
• normalize unsupported Snowflake variant:path[dynamic_expression] analysis input to the equivalent GET(variant:path, dynamic_expression) form without changing authored or executable SQL
• cover comments, quoted strings, nested brackets, validation, and the real compile CLI path

Verification

• uv sync --all-extras
• focused unit and CLI integration tests
• make check-ci
• public repository hygiene scan
