Set the terminal window title to "tig (<repo>): <view>" using OSC 0 escape sequences written directly to the tty file descriptor. The previous title is saved on init and restored on exit using the xterm title stack (CSI 22;2 t / CSI 23;2 t), which is supported by most modern terminal emulators. The repo name is derived from the git directory path by resolving it with realpath() and extracting the basename of its parent directory.

Closes #1430
Summary
tig does not set the terminal window title, making it hard to distinguish between multiple tig instances in a taskbar or window switcher. This is especially important for tiling window managers and window switchers that rely on the title to let users find windows.
This adds terminal title support using the OSC 0 escape sequence. The title follows the format
tig (<repo>): <view>(e.g.tig (linux): main) and updates dynamically as the user switches views.Details
