Add current project for indexing via editor

[G07cha]

Please describe the feature you want

Tabby supports repository level context for code completion via project indexing. To index a project I need to manually add it to ~/.tabby/config.toml, it might be handy to have a shortcut in the editor that will add a currently open project to the config file so that it can be picked up for indexing by the scheduler later.

Additional context

I primarily use VSCode so not sure if this sort of feature will be applicable to all editors Tabby supports.
