Struct TextDeltaRenderer 

pub struct TextDeltaRenderer;

Default implementation of DeltaRenderer for text content.

This implementation follows the multi-line rendering pattern used by production CLIs:

• Prefix and content on same line ending with newline + cursor up
• Content updates in-place using clear, rewrite, and newline + cursor up
• Sanitizes newlines to spaces (to prevent artificial line breaks)
• Uses ANSI escape codes for in-place updates with full line clear
• Applies consistent color formatting

Output Pattern

Full Mode (TTY with capable terminal)

[ccs-glm] Hello\n\x1b[1A             <- First chunk: prefix + content + newline + cursor up
\x1b[2K\r[ccs-glm] Hello World\n\x1b[1A  <- Second chunk: clear, rewrite, newline, cursor up
[ccs-glm] Hello World\n\x1b[1B\n       <- Final: move cursor down + newline

Basic/None Mode (colors only or plain text)

[ccs-glm] Hello\n                      <- First chunk: simple line output
[ccs-glm] Hello World\n                <- Second chunk: full content (no in-place update)
                                      <- Final: just a newline

The multi-line pattern is the industry standard used by Rich, Ink, Bubble Tea and other production CLI libraries for clean streaming output.
