Support for exclusion patterns in additional_project_paths or Project globs (e.g., !path/to/exclude/*).

We would like to have support for exclusion patterns in additional_project_paths or Project globs (e.g., !path/to/exclude/*).
We have several cases of stacks that should trigger on changes to all subdirectories (for example, the stack envs/prod should watch envs/prod/**/*.tf) except for a specific directory envs/prod/grafana, which has its own dedicated stack. Without exclusion support, we need to explicitly list every subdirectory we want to monitor. This is really difficult to maintain as subdirectories are added.Our proposed solution is to allow glob negation patterns like additional_project_paths = ["envs/prod/**/*.tf", "!envs/prod/grafana/**"] to explicitly exclude paths from triggering the stack. This would mirror the behavior of commonly used tools like .gitignore
