Tasks are fire-and-forget only: function TASK:NAME(props : dval) and
task_execute(target, timeout_seconds, props). The durable queue, the
TASK_WORKERS pool with its leases, cancellation, admission health and recovery,
task, task_status, task_await, task_cancel, the background form of shell_exec,
job_status, job_result, job_await, job_cancel, http_request_async, the job
directory and its --job-worker helper, their pages, fixtures, guide sections,
settings documentation and parity rows are gone. A bare TASK handler is a
compile error.
shell_exec(command, {on_done: "/unit.capy:NAME"}) keeps the one job use that
mattered: the command runs in the detached task runner, and TASK:NAME of the
unit receives command, exit_code, stdout, stderr, timed_out and
output_truncated when it finishes. Unit path resolution is shared by tasks and
services. The tasks guide is "Tasks and commands" with a stable slug change.

Handlers take (props : dval, request : dval) for COMPONENT and TASK and
(request : dval) otherwise; every parameter is optional and keeps its name,
and request is bound in every handler body. name : capture type fills an
omitted argument from the caller variable of that name. Exported (dval) dval
functions carry an implicit request capture. Request builtins capture
request; redirect writes request.out. The runtime builds one request value
per request, passes request and props handles to handlers, applies
request.out once after the top-level handler, and drops the pending-props
slot, handler frames, per-handler refresh, and current_request(). Core ABI
38, unit ABI 39. Legacy request type checks and the removed-API migration
table are gone from the compiler. Documentation, generated routes, tests,
and the project home follow; the home page loses the demo and starter.
