fix(zod): infer parsed tool callback arguments

Fixes #1244.

zodFunction() and zodResponsesFunction() already infer the parsed Zod output for the callback supplied in their options, but their returned auto-parseable tool types recorded the raw Zod schema type as arguments. Because AutoParseableTool and AutoParseableResponseTool use that field for their helper properties, callers saw $callback, $parseRaw, and __arguments typed as the schema object instead of the parsed tool arguments.

This updates both Zod helper return types to use InferZodType<Parameters> for arguments. The change is type-only and does not alter parsing or callback behavior at runtime.

The type regression checks now verify the inferred parsed argument type for $callback, $parseRaw, and __arguments on both chat completion and Responses API tools.

Reviewed the type flow for both Zod tool helpers and the new regression coverage. InferZodType<Parameters> matches the value returned by parseZodObject() and now propagates the parsed output type consistently through $callback, $parseRaw, and __arguments for both Chat Completions and Responses. The compareType assertions are exact, so they would fail if these properties regressed back to the schema object type.

I also validated the PR commit locally with the focused Zod suite (26 tests), pnpm build, and the full pnpm lint pipeline; all passed. No blocking issues found.
