Align the default build pin and English/Chinese build documentation with the updated module graph.

Evidence

• Before: The module and default build pin resolved Xray-core v26.10.29.
  After: Both resolve v26.10.31 (a4a3dff5b20c), also verified in the generated Android libraries.
• Passed go test -race ./... -count=1 -timeout 15m, go vet ./..., go mod verify, and git diff --check.
• All 8 build-script tests passed.
• python3 build/main.py android succeeded and restored go.mod/go.sum. All four Android ABIs contain the expected Core version and use 16 KiB ELF load alignment.

Merge Danger

Door: two-way

Blast Radius: Runtime
