Claude 0f264dd767 fix(marmot): run the interop harness, and fix what it found
The harness had never actually been run. It now builds MDK 0.9.20 —
against the same OpenMLS fork rev our vector generator pins — boots a
local relay, brings up both wnd daemons and amy, and executes all 17
scenarios. They all still fail, downstream of MDK not finding A's
KeyPackage, but "it runs" is the difference between having an interop
signal and not having one.

Four environment blockers stood between preflight and a run: protoc is
now a build prerequisite; MDK 0.9.x needs WN_ALLOW_LOOPBACK_RELAYS=1
before it will accept a ws:// loopback relay at all; it refuses to create
its socket unless the parent directory is 0700; and `wn --json whoami`
moved to {"ok":true,"result":{"accounts":[…]}}, which the harness's
extractor probed right past.

Two defects in our own code came out of it.

`amy relay add` reported success from its DECISION to write rather than
from the store's answer, so a rejected or no-op write printed
`added: yes` and the caller only discovered otherwise much later.

The more consequential one: we read our OWN relay lists back through the
local-network filter. That filter is correct for someone else's list — it
is attacker-supplied input, and it is also what exempts a relay from Tor
— but applied to a list we published ourselves it made a deliberately
configured local relay look like no configuration at all. The publisher
then fell back to a default set, and the harness sent A's KeyPackage to
five PUBLIC relays instead of its loopback, which is the exact opposite
of what a "nothing leaves the machine" harness is for. `allRelays()` now
exists for reading back our own lists; the KeyPackage publish goes only
to the configured relay.

Test 01 is still blocked on a narrower puzzle: the kind-10051 list
persists under `relay key-package set` but not under `relay add`, while
kind 10050 works through the identical code path. That is a storage/CLI
thread, not a protocol one, and it needs its own pass.

Separately, and not a bug on either side: MDK accepts ws:// only for a
loopback host while quartz strips exactly those hosts from relay lists.
No address satisfies both, so a loopback-relay harness cannot pass until
one side moves — and changing a Tor-adjacent privacy guard is a
maintainer call, not one to make in passing.
