feat: support DTS redirect

[Timeless0911]

Summary

This PR introduces a new redirect feature about DTS files.

redirect.dts

Controls the redirect of the import paths of output Typescript declaration files.

redirect.dts.path

Whether to automatically redirect the import paths of Typescript declaration output files.

• Type: boolean
• Default: true

When set to true, the compilerOptions.paths configured in the tsconfig.json file will take effect, and the import path of the DTS output file will be redirected to the corresponding relative path.

When set to false, the original import path will remain unchanged.

• Example:

When compilerOptions.paths is set to { "@/*": ["src/*"] } in tsconfig.json, the DTS output file will be redirected to the correct relative path:

import { foo } from '@/foo'; // source code of './src/bar.ts' ↓
import { foo } from './foo'; // expected output of './dist/bar.d.ts'

import { foo } from '@/foo'; // source code of './src/utils/index.ts' ↓
import { foo } from '../foo'; // expected output './dist/utils/index.d.ts'

redirect.dts.extension

Whether to automatically redirect the file extension to import paths based on the Typescript declaration output files.

• Type: boolean
• Default: false

When set to true, the import paths in DTS files will be redirected to the corresponding JavaScript extension which can be resolved to corresponding DTS file.

When set to false, the file extension will remain unchanged from the original import path in the rewritten import path of the output file (regardless of whether it is specified or specified as any value).

:::note
The extension of the TypeScript declaration file is related to the dts.autoExtension configuration.
:::

• Example:

For the .d.mts file, in some scenarios, the full extension of the module import path is needed to load correctly.

import { foo } from './foo'; // source code of './src/bar.ts' ↓
import { foo } from './foo.mjs'; // expected output of './dist/bar.d.mts'

import { foo } from './foo.ts'; // source code of './src/utils/index.ts' ↓
import { foo } from './foo.mjs'; // expected output './dist/utils/index.d.mts'
