Proposes an optional Code Mode where the model writes a TypeScript program
against a generated SDK wrapping every registered tool, instead of emitting
one native tool-call per step. Implemented Cordis-style as a capability-seam
trio (code-runtime interface / code-runtime-vm node:vm reference stub /
code-mode consumer plugin) with zero core-package changes; the hardened
execution substrate is deferred to a follow-up RFC.
