feat: Add keyboard enhancement flags, enable Shift+Enter for newline and update newline hint based on terminalS.

The keyboard enhancement protocol I added only works on terminals that support it. What terminal are you using?

• Terminal.app (macOS default): ❌ Does not support it
• iTerm2: ✅ Supports it
• WezTerm: ✅ Supports it
• Kitty: ✅ Supports it
• Ghosty: Doesn't initially works but keyboard enhancements made this work: Now ✅ Supports it
• VS Code integrated terminal: ❌ Usually doesn't support it

I tested this on ghostty but it doesn't work

[mstfash]

in my ghosty it works and I have the default ghosty settings, never changed them

• Stakpak production on ghosty does not do when pressing shift+enter. it does not even submit
• On this branch shift+enter does a new line with default ghost config
• Default ghost terminal does not even do a shift+enter for a new line with default config. you have to add them your self
