fix(zod): fix array schema traversal in getSchemaForPath

[TaekwanMin]

🔎 Overview

This PR fixes warnings that occur when describing paths for nested array fields in Zod schemas. The getSchemaForPath function was incorrectly handling array traversal, causing console warnings like:

Failed to describe path buttons[0].link on the schema, returning a default description.

The fixes include:

1. Corrected loop boundary from i <= paths.length to i < paths.length
2. Fixed array element access to use element property instead of type
3. Reordered condition checks to handle array schemas before object schemas
4. Added proper control flow with continue statements
5. Enhanced type checking functions with fallback logic for compatibility

🤓 Code snippets/examples (if applicable)

// The warning was caused by incorrect array traversal:
// Before:
if (isIndex(p) && isArraySchema(currentSchema)) {
  currentSchema = (currentSchema._def as ZodArrayDef).type;  // Wrong property
  // Missing continue, causing premature null return
}

// After:
if (isArraySchema(currentSchema) && isIndex(p)) {
  currentSchema = (currentSchema._def as ZodArrayDef).element;  // Correct property
  continue;  // Proper flow control
}

// Also fixed the loop boundary:
// Before: for (let i = 0; i <= paths.length; i++)  // Out of bounds
// After:  for (let i = 0; i < paths.length; i++)   // Correct

// Enhanced type checking for better compatibility:
function getDefType(schema: ZodSchema): ZodFirstPartyTypeKind | undefined {
  if (schema._def && (schema._def as any).typeName) {
    return (schema._def as any).typeName as ZodFirstPartyTypeKind;
  }
  // Added fallback for different Zod versions
  if (schema._def && (schema._def as any).type) {
    if ((schema._def as any).type === 'array') return ZodFirstPartyTypeKind.ZodArray;
    if ((schema._def as any).type === 'object') return ZodFirstPartyTypeKind.ZodObject;
  }
  return undefined;
}

With these changes, paths like buttons[2].link or items[0].variants[1].price are now correctly resolved without warnings.
