Fluxheim 1.5.12

Fluxheim 1.5.12 Release Notes

Fluxheim 1.5.12 starts the Fluxheim-native background task registry line.

This release is intentionally narrow. It moves Fluxheim-owned background work
behind a Fluxheim adapter while keeping Pingora only as the server registration
boundary for now.

What Changed

• Added src/background.rs with Fluxheim-owned shutdown and readiness wrappers
  for background tasks. Task implementations now see a Tokio watch-based
  shutdown handle and a one-shot readiness callback instead of Pingora
  background-service types.
• Moved cache runtime metrics, stale cache purging, ACME renewal, and the admin
  self-healing watchdog to FluxBackgroundTask.
• Moved load-balancer discovery and health refresh services through the shared
  background adapter while preserving readiness after the initial discovery
  update.
• Added regression coverage for shutdown wakeups, closed shutdown channels,
  readiness idempotence, and load-balancer readiness after the initial
  background update.
• Kept the release boundary clear: no HTTP proxy lifecycle rewrite, no stream
  listener migration, no cache interface rewrite, and no UDP/GSLB, WAF,
  VPN/firewall, or Wasm/iRules/Lua work in this tag.

Operational Notes

• Existing configuration remains compatible.
• Background shutdown behavior remains graceful and cancellation-aware.
• ACME background automation, cache purging, cache metrics, admin watchdog, and
  load-balancer refresh behavior should match 1.5.11 from an operator
  perspective.
