Abhitej John e1ce2fe131 Reclaim runner disk space before session/eval-data publish
The publish-session-data job shallow-clones the multi-GB
dashboard-session-data branch and stages the run's session logs, which
purge-replay-sessions.ps1 copies through a temp dir (transiently ~2-3x the
data). On a valid-token run that produces real trajectory logs, this can
exhaust the runner disk (System.IO.IOException: No space left on device),
which previously only surfaced when a run happened to draw a working
Copilot token and generate real session data.

Add a first-step disk reclaim (removing ~20GB of preinstalled tooling the
job never uses) plus df -h logging to publish-session-data and
publish-eval-data. Neither job runs dotnet build and pwsh 7 lives under
/opt/microsoft, so removing /usr/share/dotnet et al. is safe.
