feat: wire memory hygiene into the heartbeat loop (#195)

* feat: wire memory hygiene into heartbeat loop (#166)

* refactor: address PR review comments for hygiene wiring

* style: fix fmt import ordering and clippy too_many_arguments warning

* fix: update heartbeat integration test to pass HygieneConfig argument

HeartbeatRunner::new() now requires a HygieneConfig as its second
argument after the hygiene wiring refactor. Pass the default config
in the integration test.
