Summary

Align this runtime branch's sqlparser dependency with the merged parser backport #48.

Only three pin lines change: the workspace dependency and the two lockfile source entries. Parser features and DataFusion execution code are unchanged. This prevents two incompatible copies of sqlparser::ast when Rustice enables native DESCRIBE DATABASE/SCHEMA.

The parser backport preserves this fork's legacy VIEW AST and rejects swallowed EXPLAIN modifiers. Its source is attributed to upstream sqlparser apache#2767, with no duplicate Apache contribution.

Validation

• Parser: 1,590 passed / 0 failed / 7 ignored; strict all-target/all-feature Clippy, serde-only common-test compilation and formatting passed.
• Parser independent review: approved.
• This manifest-only diff: git diff --check passed.
• Locked offline downstream graph: one sqlparser/derive source and one coordinated DataFusion source, passed.
• Rustice downstream native qualification at local commit f1d42f1012156f7207635cc91ceac0170892bc24: 4,340 passed, zero failed, 187 existing ignored across the executor, functions, catalog, REST, catalog-metadata and role suites. Includes Service-v2 namespace metadata, rollback preservation, quoting and privilege-revocation controls.
• Independent read-only source review: approved, no blockers in the manifest/lockfile change.
• The intermediate draft Rust CI run was intentionally canceled to avoid duplicating local builds. This is downstream qualification, not a claim that the entire DataFusion workspace suite or remote CI passed.

Rustice stock-connector and strict Bronze follow-ups remain tracked in Rustice #1256; no wire or full-live-audit claim is made by this pin-only PR.

Base is df55-physical-udf-instance, the actual runtime revision used by Rustice, not the diverged default branch.
