Fix flattening zod schema - chained calls, enum value, tsConfigFilePath

[tinglei8]

There are 3 fixes in this PR:

Fix 1: Flatten chained function calls.

An example:

import { z } from 'zod';

const TypeEnum = z
  .enum(['Normal', 'Unknown'])
  .describe('Type of the item');

const FindManyInput = z.object({
  options: z
    .object({
      userId: z.string().describe('ID of the current user'),
      type1: TypeEnum.optional().describe('Type 1 of the item')
    })
    .merge({
      z.object({
        type2: TypeEnum.optional().describe('Type 2 of the item')
      })
    })
    .describe('Options to find many items'),
});

Before the fix, references to TypeEnum are not flattened in FindManyInput because it's referenced as parameters of the object() and merge() calls instead of the last describe() call.

After the fix, The TypeEnum schema is properly flattened in all places that reference it.

Fix 2: add tsConfigFilePath to module config.

See issue: #18

Fix 3: Flatten enum name to literal values.

An example:

// types.ts
export enum TypeEnum { Normal = 'Normal', Unknown = 'Unknown' };

// test.ts
import { z } from 'zod';
import { TypeEnum } from './types';

const FindManyInput = z.object({
  options: z
    .object({
      userId: z.string().describe('ID of the current user'),
      type: z.literal(TypeEnum.Normal).describe('Type of the item')
    })
    .describe('Options to find many items'),
});

Before the fix, it generates: type: z.literal(export enum TypeEnum { Normal = 'Normal', Unknown = 'Unknown' }).describe('Type of the item')

After the fix, it generates: type: z.literal('Normal').describe('Type of the item')
