Commit Message

Fix crash in error annotator when parser fails at EOF

A parse failure with a missing closing `}` at EOF (e.g.,
`context X is { ... ` with no `}` before EOF) constructs an
`At` whose `endOffset` is one past the end of the last line
computed by `lineRangeOf`. Two `require` calls in
`RiddlParserInput.annotateErrorLine` then threw
`IllegalArgumentException: requirement failed: fail: 58 >= 59`,
which the outer `runMain` catch wrapped as a SEVERE
"Exception Thrown" message, hiding the real error.

The downstream slicing already clamps via `Math.min(...,
data.length)`, so those requires were over-strict, not
load-bearing. Removed them with a comment explaining the
boundary condition.

After the fix, a missing-brace input produces a normal
Error with file location, e.g.:

  [error] badEntity.riddl(5:1->6:2):
  Expected one of ("..." | "}" | ...)

Regression test added at `TopLevelParserTest`. Fixture files
`language/input/riddl-bad/{badDomain,badEntity}.riddl` are
checked in (3 opens, 2 closes). Test asserts no Severe and
that the resulting Error mentions the file and lists `}` in
the expected-tokens set.
