test(go): ensure go unit tests pass (#16241)

## Summary Stabilizes the Go unit-test surface so the test suite can run reliably in CI and locally via \`bash build.sh --test\`. ## Verification \`\`\`bash bash build.sh --test -- -count=10 -run TestWithCancel_SequentialAgent ./internal/harness/core/ bash build.sh --test -- -count=5 -run TestSiliconflowChatExtracts ./internal/entity/models/ bash build.sh --test # full suite \`\`\` All previously failing packages (\`admin\`, \`cli\`, \`handler\`, \`parser\`, \`router\`, \`service\`, \`service/chunk\`) now build and test successfully. \`TestWithCancel_SequentialAgent\` passes 10/10 (was flaky). SiliconFlow reasoning test passes after switching the assertion to the SiliconFlow wire format. --------- Co-authored-by: Claude <noreply@anthropic.com>
