Normalize wildcard EXCLUDE targets during SQL planning

[osipovartem]

Rationale

Unquoted SELECT * EXCLUDE B fails against a derived field normalized to b (No field named B). Query planning should resolve exclusion targets with the same identifier rules as projected columns.

Changes

• Normalize unquoted EXCLUDE identifiers during SQL planning, including wildcard function arguments; preserve quoted spelling.
• Detect duplicate exclusions by resolved field name rather than identifier quote style.
• Add SQLLogicTests for unquoted, quoted, and duplicate targets, plus an integration test for the custom function wildcard planner.

Validation

• cargo +1.97.0 fmt --all -- --check
• cargo +1.97.0 clippy --locked --all-targets --all-features -- -D warnings
• Full workspace lib/tests/bins extended test suite with pinned test-data submodules
• select.slt and targeted sql_integration test
• Independent read-only review: approved; no blocking findings.

User-facing impact

Fixes wildcard EXCLUDE resolution in DataFusion 55; no API change and no execution hot-path change.
