nara: swedish for near, provides a trace from the start of the nearest virtualization
to the statement wrapped by the nara hint.
hela: swedish for whole, provides a trace from the start of the event
to the statement wrapped by the hela hint.
The eventual goal is to present these traces in a way that is most salient & useful to developers
and in a way that is aesthetically pleasing as the bout hint is useful and nice looking.
For this pull request the goal is to provide the actual functionality in code that we can feel
safe and comfortable adding to the master branch. To this end, I've added a trivial set of tests for
nara and hela in pkg/arvo/tests/run/hints.hoon - they only prove that invoking these hints will not
crash the runtime, but I'm open to ideas for how I can test these hints further.
The `ProfileOverlay` component expects a `ship` arg as a patp without the sig. This deSigs the ship value used in `NotificationText`.

+sign:schnorr crashes on `=(0 sk)`, so the bounds checking code is not
exercised for sk=0. It also crashes on `(gte sk n.domain.c)`, which is
redundant with the size check on sk, so we remove that.
The previous value—used for testing—didn't consider
block reorgs, which meant that if we zoom to the latest
block that has no transactions, but that gets later replaced
by a 1-block reorg that does have a transaction, we'll miss it,
making our Azimuth state incomplete.
To fix it, we rewind the Azimuth state to the contents of the snapshot,
and then start retrieving logs from the latest one we have.
No mark files exist for any of the drum marks, so trying to poke remote drums
would fail anyway, but relying on the mark system in that way seems a bit
fragile, so we add an explicit permission check.
No mark files exist for any of the helm marks (except `%helm-hi`), so trying to
poke remote helms would fail anyway, but relying on the mark system in that way
seems a bit fragile, so we add an explicit permission check.
