New Features

Cleaner snapshot drop
We eliminate SnapshotDropGuard, which was only protecting us half the time, in favor of a direct drop implementation on Snapshot. Misuse of the drop guard could lead to difficult to diagnose and sporadic memory leaks.
Simplify merge iterator seek
We simplify the implementation of merge iterators by removing explicit tracking of the iterator state. The iterator queue fully determines the state instead.
We also resolve the issue where a seek on a just-initialized merge iterators would cause a crash.
Fix index usage in ImmediateExecutor::find_next
Fix mixed up array index in ImmediateExecutor::find_next
Detect empty iterator queue in intersection iterator
Keep the exhausted iterator in a Done state when seeking.
Seeking on an exhausted intersection iterator just after retrieving its last element would put it in a Used state with no iterators in queue. Retrieving the next item from it would then make it panic as there is no next iterator in the queue, causing a server crash.

Speed up bazel build
Add --remote_download_toplevel to the bazel-rc for build jobs, which improves CI build times using the remote cache significantly (10-20% baseline) by not downloading intermediate rule outputs. We also allow parallelization of multiple checkstyle jobs.

Reduce diagnostics noise from CI of TypeDB users
Add a requirement for initial_delay of diagnostics reports, which, if not met, forces the reporter to skip the first report cycle. This allows silencing CI jobs built by the users of TypeDB not using the diagnostics.reporting.metrics flag without significant harm to the data (the data will be added to the next report unless the server stops early).
Additionally, clean up the diagnostics logic from the outdated code from TypeDB 2.x not used in TypeDB 3.x.
