* fix(dotfiles): allow clearing aliases, disable import
At the moment there are far too many edge cases to handle importing
aliases.
1. We need an interactive shell to print aliases. Without it, most
shells won't report much.
2. Many people have their shells print things on startup (graphics,
fortunes, etc). This could be detected as an attempt to set an alias.
Rather than spend the next year finding import edge cases, I'm
disabling it for now. There's probably a better way we can do this?
* clippy
There's a bunch of duplication here!
I'd also like to support syncing shell "snippets", aka just bits of
shell config that don't fit into the structure here. Potentially special
handling for PATH too.
Rather than come up with some abstraction in the beginning, which
inevitably will not fit future uses, I'm duplicating code _for now_.
Once all the functionality is there, I can tidy things up and sort a
proper abstraction out.
Something in atuin-client for map/list style synced structures would
probably work best.
