docs(work): decompose platform-retrofit and walking-skeleton epics
platform-retrofit: 8 stories / 18 tasks (spec bundle into docs/product,
single-version release-please before deletions, demo feature removal,
web-next auth shell, optional cores, work-tree archive, library traces,
agent-doc rewrite). walking-skeleton: 11 stories / 28 tasks across
workspaces, discovery, core-runner-protocol, runner app, editor, and
the flagship connect-to-selection e2e; builds on platform-retrofit
(prose dependency note — cross-epic frontmatter unsupported).
