v0.2.0 - Stable Cross Platform Shell

This release focuses on stability and cross-platform structure, not new shell features.

Highlights:

• Split command dispatch into a shared exec layer.
• Added a Windows execution backend and kept Unix execution support.
• Improved platform detection for Unix-like and Windows environments.
• Hardened input parsing and shell loop behavior for safer EOF and buffer handling.

Notes:

• Basic external command execution is supported on Unix and Windows.
• This is still a minimal shell, not a full cmd.exe or bash replacement.

v0.1.0 - Initial Unix Shell Release

This is the first functional release of UniverShell, marking the completion of the
initial Unix / POSIX shell implementation.

This release establishes a stable baseline for future development, including planned
cross-platform (Windows) support.
