Subject: [PATCH] fix: use run.executable instead of activatedRun.executable
 for interpreter identification

getInterpreterDetails, getSettingsPythonPath, and getExecutableCommand need
the actual Python binary path, not the activated run command. Using
activatedRun.executable breaks when environment managers set it to a wrapper
command (e.g. pixi run ... python).

This unblocks managers like conda and pixi from using wrapper commands in activatedRun without
breaking the debugger, while remaining backwards-compatible since the two
values are currently identical for all existing managers.
