fix(deps): reconcile go.sum against what the registry actually serves

Chasing these one at a time was whack-a-mole — every repair surfaced the next
moved tag (age, pq, threshold, zap, consensus, constants, sdk, keys…). This is
the systematic pass instead: every distinct luxfi/hanzoai module@version in the
workspace (692 of them) was resolved against proxy.golang.org + a direct fetch,
and any go.sum line disagreeing with what is actually served was corrected.

Not an attack, and checked rather than assumed: for each case the proxy and a
direct fetch AGREE with each other and differ from the recorded hash. Two
independent transports agreeing means nothing is rewriting bytes in flight —
the tags moved at source. sum.golang.org still holds the original, but
GOPRIVATE covers github.com/luxfi/* with GOSUMDB=off, so our own modules never
consult the checksum DB and a moved tag splits consumers silently instead of
failing at publish time.

Only the recorded hash changes. No selected version moves, and `go mod tidy`
was deliberately NOT run, so nothing is upgraded as a side effect.

Verified: `go list -m all` resolves with no checksum error.

The durable fix is upstream: treat a published version as immutable. Cut
x.y.z+1 instead of moving a tag — with GOSUMDB off, no consumer can detect it.
