Subject: [PATCH 1/2] BUILD-11553 Use RUNNER_TEMP for get-build-number cache
 file

Write build_number.txt under RUNNER_TEMP instead of the workspace
checkout so ephemeral cache state does not pollute the repository tree.

 pollution

Override BUILD_NUMBER_FILE in the spec so tests do not inherit the path
set by config-npm during the test-shell-scripts workflow.
