fb1d679f - Improve interactions with existing Python executables during install (#8733)

Improve interactions with existing Python executables during install (#8733) Previously, we'd use the `--reinstall` flag to determine if we should replace existing Python executables in the bin directory during an install. There are a few problems with this: - We replace executables we don't manage - We can replace executables from other uv Python installations during reinstall (surprising) - We don't do the "right" thing when installing patch versions e.g. installing `3.12.4` then `3.12.6` would fail without the reinstall flag In `uv tool`, we have separate `--force` and `--reinstall` concepts. Here we separate the flags (`--force` was previously just a `--reinstall` alias) and add inspection of the existing executables to inform a decision on replacement. In brief, we will: - Replace any executables with `--force` - Replace executables for the same installation with `--reinstall` - Replace executables for an older patch version by default
