* Add test for #4797: executeQueries doesn't check for nil Client
This test demonstrates that executeQueries panics with a nil pointer
dereference when Client is nil. The test currently fails with:
panic: runtime error: invalid memory address or nil pointer dereference

* Fix#4797: Add nil check for Client in executeQueries
Added a nil check at the start of executeQueries to prevent nil pointer
panics when Client is not initialized. Now returns an error message and
counts all queries as failures instead of crashing.

* Add test demonstrating bug #4781 - RunBatchSession blocks forever
Test currently skipped as it demonstrates the bug where RunBatchSession
blocks forever if initData.Loaded channel never closes, even when the
context is cancelled. This test will be unskipped after the bug is fixed.

* Fix#4781: Add context cancellation check to RunBatchSession
Changes RunBatchSession to respect context cancellation when waiting for
initialization. Previously, the function would block forever on the
initData.Loaded channel if it never closed, even when the context was
cancelled. Now uses a select statement to also check ctx.Done().

- JSON output format has changed to move the rows to under a `rows` property, with timing information under the `metadata` property
- Update timing display to show rows returned and rows fetched, as well as adding verbose mode which lists all scans
- Use enums for output mode and timing mode - timing is now either `on`, `off` or `verbose`
- Bugfix: ensure error is returned from ExecuteSystemClientCall. Closes#4246
- Execute RefreshConnections asyncronously
- Add connection_state table to indicate the loading state of connections
- Optimise RefreshConnections by cloning connection schemas
- Add locking to ensure only a single instance of RefreshConnections runs
- Start executing queries without waiting for connections to load, add smart error handling to wait for required connection
- Optimise autocomplete for high connection count
- Autocomplete and inspect data available before all conections are refreshed
- Update file watcher to respond to CHMOD, so thaat it pickes up deletion of file contents
