chore: checkpoint all prior work for clean state

Captures all uncommitted work from ha-config-bootstrap,
ha-heartbeat-liveness, and associated spec/tooling updates:

- src: ha.c, ha.h, cluster.c, config_repl.c, myapp.c, raft.c —
  heartbeat liveness, RDHUP integration, committing phase fixes
- tests: test_ha_role.c, test_config_repl.c, test_ha_rdhup_integration.c,
  test_p1_integration.c, test_p3_hardening.c, scheduler test
- specs: election-iomgr-refactor, ha-heartbeat-liveness,
  ha-peer-connection-reuse, raft-library (new); ha-config-bootstrap
  and election-iomgr-refactor task/research updates
- tooling: .wolf/ state, ha/data cluster fixtures, raft/raft.tla,
  src/build symlink, xce-build skill update
