Support ignore files

Is your feature request related to a problem? Please describe

It'd be nice to be able to automatically hide files in ignore files

Will you be willing to contribute this feature?

• Yes, I will try to implement it

Describe the solution you'd like

Support ignore files. There's this snippet from man fd describing the types of ignore files that might be useful to support:

-I, --no-ignore
       Show search results from files and directories that would otherwise be ignored by

       • .gitignore

       • .git/info/exclude

       • The global gitignore configuration (by default $HOME/.config/git/ignore)

       • .ignore

       • .fdignore

       • The global fd ignore file (usually $HOME/.config/fd/ignore )

       The flag can be overridden with '--ignore'.

I think supporting at least .gitignore and .ignore would be reasonable.

We already have a FR of "Hide specified files or directories" noted in #51.

But I don't want to impl it through .gitignore way, it will make things get complicated -- which needs iterator all parent directories recursively, ex: ~/a/b/c results in ~/a/b/.gitignore, ~/a/.gitignore, and ~/.gitignore to be found. That's a rather inefficient approach, I prefer to configure them in a certain place.

Is it really that inefficient? It only needs to check and parse ignore files in the 2-3 visible panes right? fd does this and it's still the most efficient file list tool all around.

I see ranger using a global regex to filter them. e.g.

# Which files should be hidden? (regular expression)
set hidden_filter ^\.|\.(?:pyc|pyo|bak|swp)$|^lost\+found$|^__(py)?cache__$

Due to the necessity of recursively collecting all .gitignore files before actually loading the file list, this will become the sole synchronous blocking factor for Yazi at present, especially for slower devices or network storage.

Introducing additional caching mechanisms is also required for this, necessitating an appropriate cache invalidation strategy.

Maybe we could collect .gitignore while loading the file list and apply these filters to the list once it's gathered, but this would make it more complex and result in list flickering.

# Which files should be hidden? (regular expression)
set hidden_filter ^\.|\.(?:pyc|pyo|bak|swp)$|^lost\+found$|^__(py)?cache__$

Yea that would be an ideal approach, we could expand it further though

Besides global filtering, I think it would be nice to have a way to hide files in specific directories, too. For example, Nautilus, Dolphin and Thunar use the .hidden file (https://fosspost.org/hide-files-folders-linux/) which only needs to be read for the current folder. If this would be the correct design choice for yazi however, I don't know.
