Clamp the value of Store.MeasurementsCardinality so that it can not be less
than 0. This primarily shows up as a negative numMeasurements value in
/debug/vars under some circumstances.

* fix: remove nats for scraper processing
Scrapers now use go channels instead of NATS and interprocess communication.
This should fix#23085 .
Additionally, found and fixed#23106 .
* chore: fix formatting
* chore: fix static check and go.mod
* test: fix some flaky tests
* fix: mark NATS arguments as deprecated
Fixes a race condition in the restore code path that could cause shard data restores to fail. When the race condition occurs, `Error while freeing cold shard resources` appears in the log files.
This is port of PR 22796 from master-1.x to master. Attempts at creating a test case for master failed, so the fix has ported without a corresponding unit test.

When using queries like 'select count(_seriesKey) from bigmeasurement`, we
should iterate over the tsi structures to serve the query instead of loading
all the series into memory up front.

When the compaction planner runs, if it cannot acquire
a lock on the files it plans to compact, it returns a
nil list of compaction groups. This, in turn, sets the
engine statistics for compactions queues to zero,
which is incorrect. Instead, use the length of pending
files which would have been returned.

This fix ensures that memory-mapped files are not released
before pointers into them are copied into heap memory.
MeasurementNamesByExpr() and MeasurementNamesByPredicate() can
cause panics by copying memory from mmapped files that have been
released. The functions they call use iterators to files which
are closed (releasing the mmapped files) before the memory is
safely copied to the heap.

tsdb.Engine.IsIdle and tsdb.Engine.Digest now return a reason string for why the engine & shard are not idle.
Callers can then use this string for logging, if desired. The returned reason does not allocate memory, so the
caller may want to add the shard ID and path for more information in the log. This is intended to be used in
calls from the anti-entropy service in Enterprise.
