A clearer path to the Karnelian Harness release

We are preparing the Karnelian Harness for its first final public release. The current target is January 6, 2027.\n\nBetween now and release, the work is focused on the parts that make autonomy dependable: permission boundaries, approval flows, durable memory, worker isolation, and a ledger that makes important actions inspectable.\n\nThe Download page will always show the live countdown. The final release link will appear there when the build is ready.
