fix: install managed Python on Linux filesystems

Managed Python installation rejected valid case-distinct terminfo symlinks in the pinned Astral archives on Linux x64 and arm64. Archive uniqueness now follows the target filesystem: Linux preserves case-distinct paths, while every target still rejects exact duplicates and unsafe entries.

Move the unpublished 0.12.0 bilingual release notes to the immutable-tag recovery version 0.12.1 and record the failed tag evidence.

Release note: 修复 Linux x64/ARM64 上托管 Python 因官方归档包含大小写不同路径而无法安装的问题。
