Preserve the operation[] key for cross-adapter parity.

For ?operation[]=update&operation[]=delete, TanStack passes searchParams.operation to the custom view. Next.js passes searchParams["operation[]"], so a view that reads that key can miss the filter on TanStack. Preserve the original query key before serialization.

[ERROR] 26-26: A nonliteral argument is passed to exec/execSync. Identify the receiver: Node child_process methods execute shell commands, while regular-expression and database methods have different contracts. For shell execution, prefer execFile or spawn with an argument array.

Review comment at @packages/tanstack-start/src/adapters/views/index.tsx at line
26:
Update the key normalization in the custom view adapter so serialization
preserves the original operation[] query key instead of converting it to
operation. Keep the original key available to the view for parity with Next.js
search parameters, while preserving existing handling for other keys.
