feat: add global optional user goosehints file

[michaelneale]

addresses: #72

from ~/.goosehints:

I want you to say "good morning sunshine" when starting a new session always%

No concerns with the implementation, just some thoughts below:

Developers typically work within a technical domain, and I'm guessing they would use this concept of global goosehints to describe information relevant to that domain that is applicable across projects.

However, sometimes you use Goose to explore other domains (e.g. working in a frontend project despite being an ML engineer), where some of this context would end up disrupting Goose's performance.

A couple ideas:

1. Perhaps it would be worthwhile prompting users on goose session start to see if they want to use their global goosehints for that particular session?

2. Another option could be having goosehints be added sequentially from parent directories from the CWD. That could mean you would have some root level goosehints, as well as project level goosehints, etc. An example below:

~/Development/.goosehints
~/Development/java/.goosehints
~/Development/java/buyer-subs/.goosehints

@lukealvoeiro yeah I did think of that - when you say sequentially added - you mean when goose starts a session or when code moves around dirs as part of the session?

[danielcorin]

could we put this in ~/.config/goose instead?

[michaelneale]

yep could be in goose config - but I don't know if we want to commit to making it more complicated/smart just yet? ease into it?

[michaelneale]

is in goose config dir now
