Capturing in-progress work on the harness-econ branch so nothing is stranded in
the working tree while the GitHub remote is inaccessible. Spans jouleclaw (Apple
backend + fabric detect + GGUF loader dispatch/granite-h/nemotron-h + benches),
proof (receipt jcr1 + conformance vectors + solvers), map schema, joule-code
(lockstep-quic launch notes), and new jouleclaw examples + a CI workflow.
Not a logical feature commit — a checkpoint to be reorganized/rebased later.
