The new test suite is finally complete! Now I can waste another month fixing bugs!

gh-116: Fix SPLIT handling of empty delimiter.

Rename tests/cases/passing/lcm.-fltpre to tests/cases/passing/lcm-flt.pre.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

This PR adds a comprehensive set of negative (“failing”) test cases to validate parser/type/arity error handling, and updates CI to run the new test runner script.

Changes:

Added many new tests/cases/failing/*.pre programs covering invalid syntax, invalid types, invalid arities, and runtime error conditions.
Updated CI workflow to run the PowerShell test runner (tests/test.ps1) instead of invoking prefix.exe directly.
Updated build.ps1 usage comment to reflect running from the repository root folder.

The word 'seperated' is misspelled in multiple newly added filenames (e.g., if-elseif-seperated.pre, if-else-seperated.pre, elseif-elseif-seperated.pre, elseif-else-seperated.pre). Rename them to use 'separated' to improve discoverability/searchability and avoid propagating typos in test artifacts.

This test uses single quotes for a string literal while most other tests use double quotes. If the language grammar treats single-quoted strings differently (or rejects them), the failure may not be testing the intended 'string argument to FSUM' behavior. Consider using double quotes here (and similarly in abs-type-str.pre) to keep the test focused on the type error rather than string-literal syntax.

The workflow relies on the default runner shell to execute a .ps1 script. To make this more robust and self-documenting, set an explicit PowerShell shell (e.g., shell: pwsh) or invoke the script via PowerShell (pwsh -File .\\tests\\test.ps1) so it behaves consistently if the job shell changes.
