This release adds poll_proceed and cooperative to the coop module for cooperative scheduling, adds SetOnce to the sync module which provides similar functionality to [std::sync::OnceLock], and adds a new method sync::Notify::notified_owned() which returns an OwnedNotified without a lifetime parameter.

• coop: add cooperative and poll_proceed (#7405)
• sync: add SetOnce (#7418)
• sync: add sync::Notify::notified_owned() (#7465)

• deps: upgrade windows-sys 0.52 → 0.59 ([#7117])
• deps: update to socket2 v0.6 ([#7443])
• sync: improve AtomicWaker::wake performance (#7450)

• metrics: fix listed feature requirements for some metrics (#7449)
• runtime: improve safety comments of Readiness<'_> (#7415)

This release fixes incorrect spawn locations in runtime task hooks for tasks spawned using tokio::spawn rather than Runtime::spawn. This issue only effected the spawn location in TaskMeta::spawned_at, and did not effect task locations in Tracing events.

• runtime: add TaskMeta::spawn_location tracking where a task was spawned (#7440)

• net: fixed TcpStream::shutdown incorrectly returning an error on macOS (#7290)

• sync: mpsc::OwnedPermit::{same_channel, same_channel_as_sender} methods (#7389)
• macros: biased option for join! and try_join!, similar to select! (#7307)
• net: support for cygwin (#7393)
• net: support pope::OpenOptions::read_write on Android (#7426)
• net: add Clone implementation for net::unix::SocketAddr (#7422)

• runtime: eliminate unnecessary lfence while operating on queue::Local<T> (#7340)
• task: disallow blocking in LocalSet::{poll,drop} (#7372)

• runtime: add doc note that on_*_task_poll is unstable (#7311)
• sync: update broadcast docs on allocation failure (#7352)
• time: add a missing panic scenario of time::advance (#7394)

This fixes a regression on the wasm32-unknown-unknown target, where code that previously did not panic due to calls to Instant::now() started failing. This is due to the stabilization of the first time-based metric.

• Disable time-based metrics on wasm32-unknown-unknown (#7322)

• metrics: stabilize worker_total_busy_duration, worker_park_count, and worker_unpark_count (#6899, #7276)
• process: add Command::spawn_with (#7249)

• io: do not require Unpin for some trait impls (#7204)
• rt: mark runtime::Handle as unwind safe (#7230)
