Detect WT_SESSION as a truecolor terminal in detectTerminalId so TERMINAL.trueColor agrees with the color-mode and synchronized-output detectors, fixing dull/quantized markdown swatches, LaTeX colors, and the welcome brand gradient under WSL where COLORTERM is not forwarded. Default tui.scrollbackRebuild on for ConPTY hosts (native Windows and WSL) so a scrolled-off live preview no longer leaves a duplicate above its committed final form; an explicit setting still overrides. Suppress SGR 3 (italic) under screen-family terminfo. GNU screen and tmux's screen-256color default lack `sitm`, so the multiplexer substitutes standout/reverse and paints a solid inverse block over the welcome tip, thinking traces, blockquotes, and markdown emphasis. Resolve TERMINAL.italic at runtime (with an explicit user override) and route theme italics through it, emitting plain text where slanted text is unavailable.

I was using tmux with
TERM=screen-256colorinside Windows Terminal, and the italics didn't look nice.Testing
