Add an Architecture section: the three-package workspace, core being
private and bundled, and the root-level workspace commands. New sessions
had no map of the repo.
Rewrite the MCP SDK note to warn that the advertised inputSchema must
expose .shape: a .superRefine/.refine (ZodEffects) serializes to an empty
{ properties: {} }. Document the fullSchema/parseSchema split so the
add_connection bug fixed this cycle cannot recur. Fix the stale
test/unit/helpers.ts path to its per-package location.
