Transaction Science 71cb8cbed9 http receipts: falsify the round-2 fixes
Patches (falsify/run.sh) for each fix, each failing the corpus cases it names:
legacy-group-read, walk-unclamped, fetch-unmemoised, fetch-budget-unchecked,
file-cap-unchecked, index-size-unchecked, index-items-uncapped,
index-claims-uncapped, claim-through-any-receipt, ancestor-unrecovered,
step6-skipped, figure-not-held-accepted, energy-context-assumed,
gap-coordinates-unchecked; ancestor-as-object, claim-parent-unfetched,
rcpt-name-unchecked, walk-skipped and walk-unbounded regenerated against the new
receipts.rs. Python mutations groups-from-listed, budget-unchecked and
caps-unchecked added, and the round's legacy-admitted, memo-off, walk-unclamped,
step6-skipped and ancestor-any listed in run.sh in place of ancestor-as-object.

The CLI's stream server now outlasts the deadline, so a client without the index
cap reports the deadline instead; the wall-clock assertion is dropped (the
deadline's own report is what the test reads).
