[Bug]: Expected full file match

### Which fff frontend?

Neovim plugin (fff.nvim)

### has logs

_No response_

### Description

I'm curious whether this is intended behaviour but i expected that a direct name match matches before folder / file (see screenshot)

I have:

`lsp/typos_lsp.lua`

that matches before:

`lsp.lua`

I tried clearing the cache but didnt change

Reproduce the Neovim plugin search with lsp/typos_lsp.lua and lsp.lua, checking whether the ranking consistently places the direct filename match first. Read the search-ranking implementation and existing ranking tests, if present; done means the expected ordering is defined and verified without breaking other file matches.
