fix(deps): correct moved-tag hashes for luxfi modules in go.sum

Several luxfi versions carry TWO different contents across this workspace,
because published tags were moved instead of a new patch being cut:
age@v1.5.0, pq@v1.0.3, threshold@v1.9.4, zap@v0.6.0, zap@v0.8.1.

Adjudicated before editing, since "checksum mismatch / SECURITY ERROR" is also
what a real supply-chain attack looks like. It is not one here: sum.golang.org
holds the OLD hash while proxy.golang.org and a direct fetch BOTH serve the same
NEW bytes. Two independent transports agreeing means nothing is rewriting
content in flight — the tag moved at source. The sumdb entry is a fossil:
GOPRIVATE covers github.com/luxfi/* with GOSUMDB=off, so our own modules never
consult the checksum DB and a moved tag splits consumers silently.

The old bytes are served by nothing now, so a stale pin can never build.
Corrected to the only content that exists, in BOTH line forms (h1: and
/go.mod h1:) — Go reports these one at a time, so a partial fix just relocates
the error.

Deliberately no `go mod tidy`: this changes no selected version, only the
recorded hash of versions already chosen.

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

The durable fix is upstream: never move a published tag, cut x.y.z+1 instead.
