Summary

• restore legacy mouse tracking as the framework default and only enable alternate-scroll when an app explicitly opts in and raw input is active
• move kitty keyboard negotiation into TerminaApplication, tighten parser behavior around report_all_keys, and add safer raw-input fallback behavior on Unix and non-interactive consoles
• add regression tests plus website docs for runtime input modes, raw input, alternate-scroll, kitty flags, and tmux passthrough

Validation

• dotnet build Termina.slnx
• dotnet test Termina.slnx
