Landing coordinated ts-mono changes

A change in this repo sometimes requires a matching change in the ts-mono submodule — most commonly because a Python model feeding the type-generation pipeline changed, which regenerates a file inside the submodule. Landing then requires a cross-repo dance: a ts-mono PR, a gitlink bump here, and a specific merge order. This skill is the sanctioned exception to the AGENTS.md rule against changing the submodule gitlink.
