- Remove the e2e that did concurrent mgp_* calls on the same transaction
(ATM this is unsupported)
- Fix up the concurrent mgp_global_alloc test to be testing it more precisely
- Reduce the memory limit on detach delete test due to recent memory
optimizations around deltas.
- No longer throw from hook, through jemalloc C, to our C++ on other
side. This cause mutex unlocks to not happen.
- No longer allocate error messages while inside the hook. This caused
recursive entry back inside jamalloc which would try to relock a
non-recursive mutex.
* Add AUTH system tx deltas
* Add auth data RPC and handlers
* Support multiple system deltas in a single transaction
* Added e2e test
* Bugfix: KVStore segfault after move

* Split queries into system and data queries
* System queries are sequentially executed and generate separate transaction deltas
* System transaction try locks for 100ms
* last_commited_system_ts saved to DBMS durability
* Replicating CREATE/DROP DATABASE
* Sending a system snapshot if REPLICA behind
* Passing a copy of the gatekeeper::access as std::any to all functions that could call an async execution
* Removed delete_on_drop flag (we now always delete on drop)
* Using UUID as the directory name for databases
* DBMS durability update (added versioning and salient information)
* Automatic migration from previous version
* Interpreter can run some queries without a target database
* SHOW REPLICA returns the status of the currently active DB
* Returning UUID instead of db name in the RPC responses
* Using UUIDs for database specification in RPC (not name)
* FrequentCheck forces update on reconnect
* TimestampRpc will detect if a replica is behind, and will update client's state
* Safer SLK reads
* Split SHOW DATABASES in two SHOW DATABASES (list of current databases) and SHOW DATABASE a single string naming the current database

The DoubleToString function has been updated to handle higher precision doubles correctly. The unnecessary string length restriction has been removed, allowing the function to convert the full double value without prematurely truncating it. This change ensures that the string representation of doubles is more accurate, especially for very large or very small numbers. Unit tests have been added to verify the correct behavior for a range of double values.
