release(v4.6.0): bump framework and eight skills to 4.6.0 in lockstep; archive PR #22 merge-side reviews

Issue #21 phase-1 prerequisites (PR #22) add loop runner options and the
control-plane module: MINOR. VERSIONS.md gains the v4.6.0 entry, the
archived design reviews lose their markdown trailing whitespace so
`git diff --check` is clean, and the three merge-side PASS reports
(claude, agy, codex @ 4a81d15) are archived under .agents/reports/.
