CI Implementation for Pull Requests

[cqdev-co]

Fixes https://github.com/trypear/pearai-app/issues/137

• Tested PearAI App on Windows
• Tested PearAI App on Linux
• Tested PearAI App on MacOS

Still To-Do:

• Hygeine kind of works but doesn't do much at the moment
• Only caching being done is on Linux, will continue working on Windows and MacOS so that build times for GitHub Actions will be faster

This will run on every pull request that is made to ensure that branches that are being merged to main aren't compromising the build. To allow for testing, you can also run a workflow on that particular branch.

we can fix iteratively if there are issues. its a step up from where our ci is anyways atm
