Per maintainer feedback, switches must come before files to follow
the convention: switches before files are Scryer-specific, switches
after files are application-specific.
The custom_toplevel.pl unit tests were trivial and didn't actually test
the functionality. All real testing is done via comprehensive CLI tests
in tests/scryer/cli/src_tests/custom_toplevel.md
Following TESTING_GUIDE.md, added tests at layers 2 and 3:
Layer 2 - Prolog Integration Tests (src/tests/custom_toplevel.pl):
- Test that g_caused_exception/2 is not asserted when no exception occurs
- Test that g_caused_exception/2 can be checked from custom toplevel
- Added check_for_exception/0 helper predicate for testing
Layer 3 - CLI Tests (tests/scryer/cli/src_tests/custom_toplevel.md):
- Test g_caused_exception/2 with exception thrown
- Test g_caused_exception/2 with no exception
- Test g_caused_exception/2 with error/2 terms
- Added test helper predicates in fixtures/toplevel_test_helper.pl
All tests pass successfully.

- Create Prolog integration tests in src/tests/custom_toplevel.pl
- Add CLI test configuration in tests/scryer/cli/src_tests/custom_toplevel_tests.toml
- Tests verify:
* -t halt terminates after initialization
* Custom toplevels can be user-defined predicates
* Toplevel receives control after initialization completes
* Default behavior is REPL when no -t specified
- All tests pass successfully
Following TESTING_GUIDE.md three-layer testing approach:
- Layer 2: Prolog integration tests with test_framework
- Layer 3: CLI snapshot tests with .toml configuration

Bumps the line number for the singleton warning. When the singleton
occurs on the same line at the term starts, the line number is correct:
foo(X).
However it stills mis-reports this line number as 1 instead of 5:
foo(1) :-
true,
true,
true,
Y.
See issue #1356.
This fixes#2725, by making it so that `strip_module(Pred, M, P), call(M:P)`
doesn't throw an `instanciation_error` when `Pred` isn't in the form `module:predicate`.
Now, `strip_module(hello, M, P)` will call `load_context(M)`, which unifies `M`
with the topmost module (or `user`).
Two new test cases are added: issue2725.pl, which tests the minimal case id(X) --> X.
and the strip_module(P, M, _), call(M:P) scenario, and module_resolution,
which tests the behavior of strip_module in a few scenarios.
- this re-enables line ending and file path normalization
- the latter might be unwanted, but there is only a shared flag
- this might result in too loose matching of / and \ in stdout and stderr as prolog syntax may be mistaken for a path
