Version 0.9.0

Added

• Production operations for worker draining, shutdown, queue cleanup,
  inspection, health probes, metrics, and tracing.
• Reproducible competitive benchmarks and production guidance for delivery
  guarantees, backend selection, deployment, recovery, monitoring, and
  security.
• Dashboard operations console now ships with locally vendored Alpine.js and
  Tailwind CSS assets, reusable Jinja components, JavaScript that works with a
  strict CSP, and no frontend build pipeline.
• Dashboard queue, job, DLQ, repeatable, worker, metrics, audit, and event views
  were modernized for production operations with safer actions and clearer
  state from the runtime.
• Dashboard failed job diagnostics now include redacted payload evidence, root
  cause, exception chain, stack frame summaries, raw traceback access, and
  copyable safe diagnostics.
• Dashboard reverse-proxy validation now covers root, /asyncmq/, and nested
  /operations/asyncmq/ Nginx deployments through real browser proof.
• Dashboard browser, packaging, accessibility, and scale checks now cover
  packaged assets, labeled controls, fixed desktop navigation, and bounded
  inspection of 100,000 jobs.

Fixed

• Worker reservation is bounded by execution capacity, with adaptive idle
  polling to reduce empty-dequeue pressure.
• Lifecycle transitions now reject stale claims and cover completion, retry,
  cancellation, expiration, delayed promotion, cleanup, and DLQ movement.
• Stalled recovery releases abandoned active jobs while preserving terminal
  states after persistent backend restarts.
• Backend semantics are aligned for priority/FIFO ordering, delayed jobs,
  dependency blocking, pause/resume, retries, cleanup, and restart handling.
• Redis scalability improves with waiting queues indexed by ID, compact lifecycle
  metadata, and compressed large payload storage.
• Worker, scheduler, dashboard, CLI, sandbox, and security defaults were
  hardened for production operation.
• Dashboard links, redirects, and same origin checks now stay correct under
  mounted paths and trusted reverse proxies.
• Dashboard overview and queue live updates now run from packaged JavaScript
  instead of inline scripts.
• Dashboard metrics and DLQ controls now avoid inline scripts and unsupported
  per-row AJAX routes.
• Dashboard responses now include strict security headers and a CSP without
  inline script or style allowances.
• Dashboard job lists now consume an inspection page contract owned by the runtime and
  clamp page sizes.
• Dashboard desktop shell now keeps the navigation fixed while the content
  workspace scrolls independently.
