feat(harness): add code-sonnet-direct composite + direct-push context

Copies code-sonnet-direct/v1 (composite) and direct-push/v1 (context)
from agent-runtimes local harnesses to the CRS-served framework repo.
These are required by the sonnet-integrator task template used in the
ralph coding loop. Without them, all integrator dispatches fail with
"harness not found in any concepts repo: code-sonnet-direct/v1".
