Implement managed Team Library lifecycle, permission-scoped same-team/cross-team retrieval, layered assignment context admission, provider context overflow handling, current logical TreeDX access, and reliable knowledge publication/replication.\n\nAcceptance:\n- Team libraries are provisioned, protected, reconciled, and deleted with their team.\n- Cross-project reads and cross-team grants remain read-only and permission bounded.\n- Required context fails closed; overflow makes incompatible offers ineligible.\n- TreeDX reads use current logical paths by default.\n- Publication uses canonical refs and operation priority prevents mirror backlog starvation.\n- Control-plane tests and distribution build pass.
