test(core): cover the error-reporting paths

Coveralls was failing the PR: the new error machinery had no tests of
its own, and it was reached only incidentally by tests aimed at other
things. `format`, `parse` and the two branches in `diagnose` that pick
the context over the result — the ones that make an error point at the
furthest offset rather than where parsing stopped — were the gaps that
mattered, since that behaviour is the reason the release exists.

Adds `format.test.ts` and `parse.test.ts`, and covers the left-recursion
guard in `grammar`, the committed branch of `label` that keeps the inner
error, and `take`'s singular/plural wording.

Also drops an unreachable fallback in `format`: `line - 1` is the number
of newlines before the offset and `split('\n')` always yields one more
entry than that, so the index is never out of range.

Statements, branches, functions and lines are all at 100%.
