You're right, removed. SGR 0 resets everything including colors. |

pr nushell#992 reset stale sgr state before each repaint, which fixed prompt color bleed from previous command output. it did not fix the starship case reported in starship#6560 and nushell#16384 because reedline still applied its own default prompt colors immediately before printing the prompt. that meant a prompt implementation that returned ansi text without overriding `get_prompt_color()` still inherited reedline's defaults. for starship, `style = "none"` emits no color sequence at all, so the first visible character inherited reedline's green prompt color instead of the terminal's foreground color. change the default prompt, multiline, indicator, and right-prompt colors to the terminal defaults. prompts that want explicit colors can still override the color methods, but unstyled prompts now stay unstyled and no longer need an extra reset sequence to avoid the green first character.

Summary
Reset any ANSI styling that may have been left by external commands before printing the prompt. This ensures the prompt is not affected by previous output styling that was not properly reset.
Problem
When external commands output text with ANSI styling but don't include a reset sequence, the styling continues to affect the prompt display. This was reported in nushell/nushell#16384.
Solution
Added ANSI reset (
SetAttribute(Attribute::Reset)andResetColor) at the beginning ofrepaint_buffer()function to ensure any leftover styling is cleared before the prompt is rendered.Test Plan
Fixes nushell/nushell#16384
