[ux] Ctrl+P / Ctrl+N not mapped for input history navigation; no /terminal command

[shreyastelkar]

Problem

Standard terminal keybinds Ctrl+P (previous history) and Ctrl+N (next history) are not mapped in the TUI input. Only Up / Down arrow keys work for history navigation. There is also no /terminal command to configure terminal behavior or keybind presets.

Expected behavior

• Ctrl+P should navigate to the previous input history entry (same as Up arrow)
• Ctrl+N should navigate to the next input history entry (same as Down arrow)
• These are readline/emacs-standard keybindings that terminal-native users expect by default

Current behavior

• Ctrl+P and Ctrl+N do nothing
• Only Up / Down arrows work for history (documented in keybinds page)
• The keybinds are customizable via config, but Ctrl+P / Ctrl+N should be defaults — not something users have to discover and manually configure

Additional context

• The keybinds docs list 85+ configurable keybindings but omit Ctrl+P / Ctrl+N from defaults
• No /terminal command exists in the built-in commands to adjust terminal behavior presets (e.g., emacs-style vs vi-style input)
