A lease row had no reconcile path at all, and nothing failed to say so.
`cleanup.js` resolves a resource to the action of the step that made it, and for
a lease that action is `core.lease` -- a CORE action, on a path a module cannot
register anything on. So every `override` row came back `unanswered` for the life
of the run, and a lease the shard had quietly dropped (a config lease is
memory-only there, so a restart reverts it by design) stayed in the ledger as
live until teardown went hunting a baseline nobody was holding.
`core.lease` gains a `reconcile()`, and `registerEventLeases` gains an optional
`inForce()`: "does the game side still have any record of this hold?"
Deliberately not `read()` plus a comparison. A value that differs from what the
run applied is DRIFT, which teardown must deliver through `restore()` so the row
lands `drifted` with the current value beside it; a reconcile that inferred
absence from a changed value would orphan the row first and tell the operator the
lease vanished rather than that somebody moved it. Only an explicit
`{ ok: true, held: false }` takes a row out -- a throw, a timeout, an
unrecognised shape and a lease with no `inForce()` all leave the ledger alone.
MODULE_API_VERSION stays 1.10.0, amended in place.
