fix(on): bump relayfile-mount binary v0.1.6 -> v0.7.39 (#982)

The cloud Daytona persona path downloads the relayfile-mount Go binary at
RELAYFILE_VERSION (version-checked cache re-downloads on a bump, so no
snapshot swap needed). v0.1.6 predates the workspace-export 413->paginate
fallback (relayfile v0.7.33/#195) and scoped mount-path support (v0.7.39/#206),
so large repos (e.g. AgentWorkforce/cloud) bulk-export >128MB -> HTTP 413 ->
starve the sandbox bootstrap (bootstrap_timeout). v0.7.39 pulls both fixes.

Unblocks AgentWorkforce/cloud#1028. (Pairs with relayfile#207 restoring
checksums.txt on releases + the backfilled v0.7.39 checksums.txt asset, which
verifyChecksum() requires.)
