156 refactor into workspaces (#157)

* chore: Major refactoring

Still needs a massive go-over because there shouldn't be anything referencing tauri in any of the workspaces except the original one. Process manager has been refactored as an example

Signed-off-by: quexeky <git@quexeky.dev>

* fix: Remote tauri dependency from process

Signed-off-by: quexeky <git@quexeky.dev>

* refactor: Improvements to src-tauri

Signed-off-by: quexeky <git@quexeky.dev>

* refactor: Builds, but some logic still left to move back

Signed-off-by: quexeky <git@quexeky.dev>

* refactor: Finish refactor

Signed-off-by: quexeky <git@quexeky.dev>

* chore: Run cargo clippy && cargo fmt

Signed-off-by: quexeky <git@quexeky.dev>

* refactor: Move everything into src-tauri
