feat(xray): update xray-core to v26.10.31

Bump xtls/xray-core to a4a3dff5b20c (v26.10.31) and the three binary
pins in DockerInit.sh and release.yml in lockstep, so the in-process
conf.Build() validation and the child binary agree. The other Go
modules move to their latest patch/minor releases in the same go.mod.

26.10.31 moved ResolveLuaFile from common/platform to
common/platform/filesystem; childLuaScriptPath now calls it there. The
lookup order is unchanged, the extension check is now case-insensitive.
