Adriano Machado updated CAMEL-23830:
------------------------------------
Description:
In the embedded shell panel (camel-jbang TUI, ShellPanel), text echoed while
typing a command, and error output such as "Unknown command: x", render in a
dark red (~RGB 136,0,0) that is hard to read on dark terminal themes. The
prompt itself renders fine (camel in orange, version in green, > in white).
Root cause: JLine command highlighting colors unrecognized commands with ANSI
red (index 1), and JLine ScreenTerminal encodes named ANSI colors as a
4-bit-per-channel RGB value. ShellPanel.convertAttrToStyle reconstructs that as
a literal dim RGB instead of a terminal-themed named color. Elsewhere
(TuiHelper) the TUI uses Color.ansi(AnsiColor.RED) so the host terminal applies
its theme and stays readable.
Acceptance: command echo and shell error output are legible on dark and light
terminal themes, consistent with how other TUI components render ANSI colors.
