`permalink :title` changed without backward-compatible replacement

### Check List

- [x] I have already read [Docs page](https://hexo.io/docs/) & [Troubleshooting page](https://hexo.io/docs/troubleshooting).
- [x] I have already searched existing issues and they are not help to me.
- [x] I examined error or warning messages and it's difficult to solve.
- [x] I am using the [latest](https://github.com/hexojs/hexo/releases) version of Hexo. (run `hexo version` to check)
- [x] My Node.js is matched [the required version](https://hexo.io/docs/#Required-Node-js-version).

### Expected behavior

In the latest Hexo update, the `:title` permalink no longer matches the post's file path as it used to.
This change breaks existing post URLs for users who relied on the previous behavior, and there is currently no replacement option to maintain the old permalink structure.

This impacts blogs that have been live for years, causing broken links and SEO issues.
Please consider providing a backward-compatible replacement or a setting to restore the previous behavior.

### Actual behavior

Currently, the :title permalink is no longer based on the post's file name under `source/_posts/`.
Instead, it appears to be generated from the `post-folder-post-filename`, causing the permalink to differ from the expected file-based path.

### How to reproduce?

1. install hexo etc
2. in `_config.yml` set permalink to `:title.html`

### Is the problem still there under `Safe mode`?

Yes
