This PR fixes CocoaPods version-list parsing to avoid selecting the wrong pod when one pod name is a prefix of another (e.g., Foo vs FooBar) by requiring an exact field match when scanning the versions index.

Changes:

• Update CocoaPods version-line matching to require "{name}/" instead of a plain prefix match.
• Add tests covering overlapping-name scenarios and the “no exact match” case.

• get_cocoapod_tags() can return None (no exact match or exception). The primary caller get_cocoapods_data_from_purl() iterates for tag in data_list without checking for None, so a missing pod entry will now raise TypeError: 'NoneType' object is not iterable instead of cleanly yielding no results. Consider making this helper always return a list (empty when not found / on error) and avoid the bare except: (it also catches KeyboardInterrupt/SystemExit).

            if line.startswith(name + "/"):
                data_list = line.split("/")
                if data_list[0] == name:
                    data_list.pop(0)
                return data_list
