Efficient common case for setCurrentTime

Efficient common case for setCurrentTime

KnownPeers.setCurrentTime and EstablishedPeers.setCurrentTime run on
every governor loop iteration. Add a fast path to KnownPeers for the
common case where nothing is scheduled or the earliest scheduled time
is still in the future; previously it always ran the general path,
rebuilding the record and (with +asserts) checking the invariant.

In EstablishedPeers use findMin instead of minView in the existing
fast-path guard: an O(1) peek that avoids allocating the deletion of
the minimum. The fast path now also covers the empty-queue case, which
previously fell through to the general path.

We only need Eq.

Bumps the pinned tag to include the runTracerA INLINE fix.

Without INLINE, every traceWith call with a nullTracer (Squelching
constructor) allocates a fresh Kleisli wrapper via arr (const ()).  In
the network-mux bearer hot path this amounts to 5 such calls per SDU.
With messages chunked into 1260-byte SDUs, a single 3 MB payload
generates thousands of SDUs and therefore thousands of spurious Kleisli
allocations per traceWith call, producing hundreds of MB of short-lived
GC pressure that pushes the test suite past the 900 MB Hydra limit.

With INLINE on runTracerA and the existing INLINE on traceWith, GHC
reduces traceWith nullTracer x to pure () at the call site: zero
allocation, no GC overhead.

This reverts commit 85d7de79ea8bda2dfa5daf2962a7de566c86d983.

* Log stat header.
* Formatting stat header & StatPoint.
* Start logging ping statistics / tip / query results only when all clients are ready.  This way we
  don't mix connection messages / warnings with other messages.

Bold headers are printed when color output is enabled (always, or auto
when stdout is a terminal).

Change the time for each call so that ghc is forced to run every loop
itteration.
