`rotateLeft` and `rotatedLeft` raised `DivByZeroDefect` for empty
containers because their whole-container overloads computed `dist mod
arg.len` before checking for an empty input.
Handle empty inputs explicitly:
- `rotateLeft` returns `0` and leaves the container unchanged.
- `rotatedLeft` returns an empty sequence.
Add a regression test covering both overloads.
The slice overloads are intentionally left unchanged because zero-length
slice semantics need separate consideration.

Each test must have a filename of the form: t*.nim
Note:Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile - compiles the module and fails the test if compilations fails.
run - compiles and runs the module, fails the test if compilation or
execution of test code fails.
reject - compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
