chore: perpare 1.52.0 (#8045)

# 1.52.0 (April 14th, 2026)

## Added

- io: `AioSource::register_borrowed` for I/O safety support ([#7992])
- net: add `try_io` function to `unix::pipe` sender and receiver types
  ([#8030])

## Added (unstable)

- runtime: `Builder::enable_eager_driver_handoff` setting enable eager
  hand off of the I/O and time drivers before polling tasks ([#8010])
- taskdump: add `trace_with()` for customized task dumps ([#8025])
- taskdump: allow `impl FnMut()` in `trace_with` instead of just `fn()`
  ([#8040])
- fs: support `io_uring` in `AsyncRead` for `File` ([#7907])

## Changed

- runtime: improve `spawn_blocking` scalability with sharded queue
  ([#7757])
- runtime: use `compare_exchange_weak()` in worker queue ([#8028])

## Fixed

- runtime: overflow second half of tasks when local queue is filled
  instead of first half ([#8029])

## Documented

- docs: fix typo in `oneshot::Sender::send` docs ([#8026])
- docs: hide #[tokio::main] attribute in the docs of `sync::watch`
  ([#8035])
- net: add docs on `ConnectionRefused` errors with UDP sockets ([#7870])
