PythonInfo.discover_exe()reused a prefix lookup result without considering the requested version. A caller that resolved one virtual environment could then receive that version's metadata for a different interpreter. The cache key now includes the requested version, so the second lookup checks candidates for its own version. Fixes #186.The lookup cache omitted the version
The previous cache key contained only the prefix and exact-match flag. The new key includes
version_info. This keeps results from one requested version out of lookups for another version under the same prefix.Behavior changes
A lookup for a different version may interrogate candidates even when the prefix was searched earlier. Lookups for the same version still reuse the cached result. In the reported case, the second 3.11 request returns no match instead of reporting a 3.15 executable as 3.11.
