Support recursive CTE CYCLE clauses and share recursive clause rendering

[minleejae]

Recursive queries using PostgreSQL CYCLE currently fail after the CTE body. Add WithCycleClause with ordered cycle columns, the mark and path column names, and optional TO/DEFAULT expressions. SEARCH followed by CYCLE, implicit Boolean defaults, multiple CTEs and quoted names are supported.

WithItem now shares SEARCH/CYCLE suffix rendering between its model output and SelectDeParser. Expression callbacks let custom deparsers visit the key and mark expressions. The select visitor adapter, table finder and validator traverse the new clause.

Validation:

• Full Gradle check and Maven verify.
• Roundtrip/AST tests for six clause variants, malformed clauses, multiple CTEs and custom expression visitors/deparsers.
• Six recursive SEARCH/CYCLE variants executed against an actual cyclic graph on PostgreSQL 18.
