feat(ai-term): render Claude Code session colors in dupre hues

Claude Code's /color picks a session accent from eight names, each emitted as a fixed xterm-256 index (probed against v2.1.198 by cycling /color in a scratch tmux session and reading the SGR codes). Agent terminals now pin all eight indices plus the bypass banner to dupre faces, so any /color choice renders in the theme's palette instead of stock xterm hues. dupre has no orange or pink, so those borrow red+1 and magenta+1. If a Claude Code update moves an index, the stock hue comes back (the alist docstring carries the re-probe note).
