punk::console models two channels per console ({in out}); its own
diagnostics fall back to raw puts stderr and subshell/backend/theme goals
(G-001/G-008/G-009) inherit the dual-channel assumption. G-011 defines err
as an attribute of the canonical {in out} console identity: {in out err}
specs accepted everywhere -console is, a nullable err field on
opunk::Console, err defaulting to process stderr for the default console
and to the console's out channel elsewhere, console-directed diagnostics
and an emit-to-err path, and cross-thread discovery via console_fact_get.
Ownership/fact/mode-cache keys stay canonical {in out}, so the G-007 work
is untouched.
Detail file records the gap analysis, the rejected shapes (err-in-identity
triple key, scope-boundary-only, uniform err==out, unset-means-none) and
the G-001 sequencing interaction.
