ci: install pql in the test / integration / bundle jobs

The daemon pql command tests (test/daemon/pql_commands_test.dart, 36 cases)
shell out to the real pql binary, and the app boot exercises it too — GitHub
runners don't ship pql. Every prior run failed in the parallel pool before
reaching the serial pass that holds these tests; now that the pool is green,
they surface. Download the latest pql Linux release onto PATH in the three jobs
that run tests / boot the app. (The repo is pql-centric; this also future-proofs
adding the decisions gate to CI.)
