refactor: migrate /opt/gh-aw paths to ${{ runner.temp }}/gh-aw for self-hosted runner compatibility

Changes /opt/gh-aw to ${{ runner.temp }}/gh-aw across the codebase so that
self-hosted runners without write access to /opt can run workflows.
Updates Go constants, setup action, golden files, lock files, and tests.
