v2.5.0

Task runs can queue other task runs and the chain is recorded on every run,
CPU bound tasks behave the same way in a subprocess as on the event loop, and
Kubernetes Jobs inherit the task timeout. The documentation gained a settings
reference, a recipes cheat sheet and a page on pointing coding agents at the
library.

• A task run can queue another task run with
  TaskRun.queue, which
  records the queueing run in from_run_id and carries the root_run_id of
  the first run in the chain, so any run can be traced back to the one that
  started it.

• CPU bound tasks now start the async event dispatcher in the subprocess that
  runs them, so lifecycle events reach the handlers and plugins there as well,
  and a consumer with CPU bound tasks that is not started from
  TaskManagerCLI raises the
  new CpuBoundEntryPointError on startup rather than failing when the first
  such task runs.
• A Kubernetes Job created for a CPU bound task sets active_deadline_seconds
  from the task timeout_seconds, so the cluster terminates a Job that
  overruns.
  (#108)
• New Settings reference
  page covering the environment variables that configure the task consumer,
  broker, database and HTTP client, including the prefix rules and the fields
  that keep an unprefixed name.
• Fixed the Task Broker
  tutorial, which imported a name that does not exist, quoted the wrong
  default Redis port, and listed six outdated abstract methods instead of the
  sixteen a broker has to implement.
• Admonition blocks are rendered as admonitions instead of literal text, which
  also fixes the note on retry delays in the
  Task Retry reference.
• New recipes cheat sheet, a page on
  using the docs with AI agents and
  an AGENTS.md for contributors.
  (#111)
• New tutorials on
  task dependencies,
  choosing a task manager
  and extending the FastAPI app.
  (#109,
  #111)
• New comparison page placing the
  library next to Celery, RQ, arq and taskiq, with download numbers refreshed
  by a scheduled workflow, and a landing page rewritten around CPU bound work.
