## Which issue does this PR close? Closes no issue. ## Rationale for this change Snowflake permits nested semi-structured paths in staged COPY transformations, for example `$1:country:name::VARCHAR`. The dedicated simple staged-field parser currently consumes `$1:country` and leaves `:name::VARCHAR` behind, so the documented statement fails to parse. Documentation: https://docs.snowflake.com/en/user-guide/tutorials/script-data-load-transform-parquet ## What changes are included in this PR? - Fall back to the standard expression parser when a staged field is followed by another path operator, bracket access, qualification, or cast. - Extend the existing COPY cast-transformation test with the documented nested-path shape. Simple staged fields keep their compact `StageLoadSelectItem` AST; only complex expressions use the existing `JsonAccess` / `Cast` AST. ## Are there any user-facing changes? Yes. Snowflake COPY statements with nested staged paths now parse and round-trip correctly. ## How was this change tested? - `cargo test --test sqlparser_snowflake` (164 passed) - `cargo clippy --all-targets --all-features -- -D warnings` - `cargo fmt --all -- --check` -- This is an automated message from the Apache Git Service.
