design: separate objects + delta-table-owned reclock (drop the atomic RECORDER bundle)

Record the model decisions: RECORD/INTEGRATE/prune are separate,
independently-created/dropped objects over DELTA TABLEs -- NOT one atomic
RECORDER bundle. Cross-object consistency comes from reading at a common logical
time; each object commits via a frontier-gated OCC write (compute through X,
commit at X+1), which is also what makes the split-object dedup safe (the prune
sees finalized data <= X). The DELTA TABLE names its domain and owns its reclock;
INTEGRATE reclocks by the delta table's reclock (one writer commits data+reclock
together). Updated surfaces, dependencies, MVP, feasibility, open questions; and
the impl doc's architecture fork (per-object control-plane commit, no
multi-output bundle), risk register (H3 object model demoted to Med), and phased
plan. Drops the agent's gaps that the logical-time/frontier framing dissolves.
