Bump version to 0.4.1-surreal.1

Upstream `tikv-client 0.4.0` was published to crates.io on 2026-02-07
(no `v0.4.0` git tag; same vulnerable dep stack as 0.3.0). Naming our
release `0.4.0-surreal.1` would be a semver pre-release of upstream's
0.4.0 and sort *below* it, which inverts the actual signal — our fork
is past upstream's 0.4.0, not a prerelease of it.

Bump to 0.4.1-surreal.1 so the version sorts above upstream and the
`-surreal.N` suffix continues to mark fork-only releases.
