Add wildcard support for exclusion rules

**Is your feature request related to a problem? Please describe.**
Right now, if I want to ignore multiple packages from the same project, I have to list each one individually. And the rules need to be updated any time a new package from that project gets added. This can be a bit cumbersome.

**Describe the solution you'd like**
Add wildcard support to the exclude rules, so something like `exclude('project:*')` would work.

**Describe alternatives you've considered**
Excluding each individually.

**Additional context**
N/A

Start by locating the exclude-rule implementation and its existing tests, then trace how package identifiers are matched. Confirm the expected behavior for a pattern such as `project:*`, including whether it matches all packages in that project, and add coverage showing wildcard exclusions work without listing each package.
