Config per window / panel / path instance, instead of one across all windows

[lofimichael]

Hi there!

I'd like for the ability to selectively apply certain configurations (i.e. fonts, shaders, etc.) per window/panel, or per detected directory.

Alongside one global config, having idiosyncratic configs be applied (i.e. if terminal path matches XYZ, apply config-1-path, etc; in this example, by default, all windows use a wildcard path and thus the default config path).

As a Claude Code user, I enjoy having two different projects open at once - one for writing, and another for code implementation; having different font sets, panel borders, aesthetics, etc. for these in the same Ghostty application instance would be delightful.

(I recognize this probably introduces a sort of "shouldUpdate" check on changing directories if enabled, which does have some performance implications, but one I am perfectly fine as a user with configuring/accepting myself)

Made a PR for this:

Rather than making Ghostty react to the CWD (which comes with its own suit of problems regarding e.g. local and remote machines) I think a better way of implementing this would be to use something like Direnv to run scripts when the user switches into a specific directory, which can change Ghostty's configs on the fly via #2353.
