Terminal Version (XTVERSION)
XTVERSION (CSI > 0 q) requests the terminal's name and version string. The response is DCS > | name(version) ST. This allows applications to identify the exact terminal and version at runtime, enabling precise feature detection beyond what TERM or DA responses provide. Originally an xterm extension, now supported by many modern terminals including Ghostty, WezTerm, foot, and kitty.
How this is tested: Send CSI > 0 q, verify the terminal responds with a DCS > | version string.
