ci: provision Pi runtime 0.84.1 in the test step (Invariant R)

invariant_r_unittest.py (landing with the lease-remediation stack, PR
#1109) hard-requires an installed `pi` binary pinned to the measured
version: it boots Pi's real tool registry and proves the broker's
read-only carve-out resolves to real, unshadowed builtins. Absent
runtime fails loud by design — so CI must provide it.

Install @earendil-works/[email protected].1 (the canonical Pi;
@mariozechner/* is embedded-legacy) at step level in the test step.
Step-level rather than baked into Dockerfile.ci because ci-image
publishes are currently blocked on registry UNAUTHORIZED; baking it in
is the follow-up once registry auth is fixed, at which point this line
degrades to a fast no-op guard like the openssl line above it.
