Bypass agent ENTRYPOINT in rootless artifact permission repair

[Copilot]

Rootless artifact permission repair was invoking the agent image without overriding its ENTRYPOINT, so the repair command never ran and each directory incurred a deterministic ~30s timeout. This change routes the repair through sh directly so chown/chmod executes as intended and preserves actionable failure details when errors are emitted on stdout.

• Repair path correction (core fix)

  • In fixArtifactPermissionsForRootless(), docker run now sets --entrypoint sh.
  • The command is passed directly as -c 'chown ...; chmod ...', avoiding entrypoint.sh/iptables wait logic entirely.

• Failure observability

  • Non-zero exits now report stderr, with fallback to stdout when stderr is empty.
  • This surfaces timeout text from stdout-only failure modes instead of logging an empty-detail warning.

• Contract coverage updates

  • Updated tests to assert the new invocation shape (--entrypoint sh, -c ... command).
  • Added coverage for stdout-only failure logging behavior.

// before: image ENTRYPOINT intercepted this
docker run ... <agent-image> sh -c 'chown ...; chmod ...'

// after: run repair command directly in shell
docker run ... --entrypoint sh <agent-image> -c 'chown -R "$TUID:$TGID" /fix 2>/dev/null; chmod -R a+rwX /fix'

• Fixes Rootless artifact permission repair never runs: agent image ENTRYPOINT hijacks the repair command and adds an exact 30 s failure per directory #6334
