jenkins d3cb6e9045 hermes(hux): add contract-only foundation for the chat UX program
Schemas, examples and a flag registry for the twelve HUX cards, a dependency-free
validator, the governance rules (memory ledger, autonomy matrix, friendly modes
mapped to real Switchyard routes, privacy defaults, suggestion gating, release
state machine) and the contract doc UI work codes against.
