Note that this is only for parsing OSC 3008. Should be structured similarly to the way various Kitty extensions are parsed (see #10467 and #10560) or the way OSC 133 sematic prompts are parsed.

Discussed in #10889

Would be interesting to implement support for https://uapi-group.org/specifications/specs/osc_context/

All of systemd's tooling sends OSC-3008 signals. Which allows Terminal Emulators like ghostty to keep track of the stack of processes that have current control over the tty
