Update to Substrait v0.95.0

[substrait-project-bot]

Release Notes

0.95.0 (2026-06-28)

⚠ BREAKING CHANGES

• grammar: Fixes operator precedence when parsing return type expressions from extension YAMLs. This can be breaking for user defined extensions YAMLs which may have relied on the faulty operator precedence parsing behavior which is now fixed to use conventional operator precedence.
• protos: removes deprecated Type.user_defined_type_reference field

Features

• protos: remove deprecated Type.user_defined_type_reference field (#1095) (0cdad6d)

Bug Fixes

• grammar: give binary operators conventional precedence (#1107) (d4eee3d)

Implemented by #204 (spec bump to 0.96.0).

• Type.user_defined_type_reference removal absorbed — zero references in src/ (code uses user_defined).
• Conventional operator precedence (#1107): the 0.95 grammar split BinaryExpr into MulDiv/AddSub/Comparison/Equality/And/Or; derivation_expression.py was migrated to walk the per-operator contexts. Verified: evaluate("2 + 3 * 4") == 14 and evaluate("2 * 3 + 4") == 10.
