Equivalence Reasoning

stylistic

The agent patch implements MySQL parsing for both `ALTER TABLE ... RENAME TO` and `... RENAME AS`, stores which keyword was used (`To` vs `As`), and updates `Display` to emit the original form, preserving round-tripping intent. It also adds/updates tests accordingly. Differences from gold are structural (separate keyword field vs wrapped enum), not behavioral.

Code Review

correctness: 3/4edge case handling: 3/4introduced bug risk: 3/4maintainability idioms: 3/4

The patch largely implements the requested MySQL `ALTER TABLE ... RENAME AS` support and preserves keyword round-tripping, but there is a plausible behavior mismatch from restricting `AS` parsing to MySQL-only in this code path.

1 finding
Dialect-gated `RENAME AS` may be stricter than expected parser behavior
major

The parser now accepts `RENAME AS` only when `dialect_of!(self is MySqlDialect)`. If expected behavior is to parse this syntax in shared parser contexts as well (while documenting MySQL as origin), this can cause mismatches.
