📝 WalkthroughWalkthroughPostgreSQL and SQLite now reject non-finite numeric ChangesPagination validation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change rejects non-finite direct LIMIT/OFFSET values, but expression-form pagination can still produce invalid SQL instead of the expected error in both adapters. This is a bounded correctness gap that should be addressed or explicitly accepted before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

SelectAst.limit and SelectAst.offset before renderLiteral in both PostgreSQL’s
SQL renderer and SQLite’s adapter; reject NaN and ±Infinity with
RUNTIME.AST_INVALID while preserving valid pagination rendering, and add
regression tests covering both adapters.

Validate expression-form pagination values.
SelectAst.limit and SelectAst.offset accept AnyExpression. A LiteralExpr containing NaN or Infinity bypasses the primitive-number check, reaches renderLiteral, and becomes invalid SQL such as LIMIT NaN without RUNTIME.AST_INVALID. Apply the finite-number validation before expression rendering in both adapters and add regression tests.
