feat(share): render colors in the shared terminal — 0.24.0

The terminal view rendered monochrome (QPlainTextEdit.setPlainText), dropping
pyte's per-cell attributes. Rewritten as a QTextEdit that renders fg/bg/bold/
reverse per cell (block cursor = inverted cell), preserving scrollback. The
session already runs the host's $SHELL + config with TERM=xterm-256color, so
fish/ls/git/prompts now look the same as locally.

+## [0.24.0] - 2026-05-22
+### Added
+- **Shared terminal is now in color.** The terminal view renders pyte's per-cell foreground/
+  background, bold, and reverse, so the host's real shell keeps its theming — fish, `ls`,
+  `git`, prompts, etc. look the same as locally (the session already runs the host's `$SHELL`
+  with its config and `TERM=xterm-256color`; only the rendering was monochrome).

 ## [0.23.0] - 2026-05-22
 ### Added
 - **Crash-logger trigger modes (M9 / D6)** via `systemd --user`, no root: **manual**,
