IELTS Codex v0.6.2

Fixed

• Fixed APT package detection so interpreter names such as python3.12 are matched exactly. Missing Python packages can no longer be mistaken for similarly named packages such as PostgreSQL Python extensions.
• Added an interactive Ubuntu fallback when configured APT repositories have no Python 3.10+ package. Before adding ppa:deadsnakes/ppa, the launcher explains that it is third-party and requires an explicit y; declining leaves package sources unchanged.

Verification

• 99 tests passed.
• Bash syntax, default interpreter selection, explicit interpreter selection, and exact APT matching were checked.
• The release wheel was built and verified to report version 0.6.2.
• README demo GIF was recorded from the real 0.6.2 CLI.
