Let Equals match a number against a typed number like 130 (#224)

The float tolerance from the last commit never reached the case it was
built for. The inputs of Equals are of type any, and their inline field
is a text field. A typed 130 therefore arrives as the string "130", and
the tolerance only applied when both sides were real numbers. The node
fell back to comparing "129.99999999999997" with "130" as text.

- A number against a text that parses as a number now uses the same
  1e-9 rule as two numbers.
- An empty text does not count as 0.
- Two texts are still compared as text, so "1.0" and "1" stay
  different.
- Compare was not affected, its inputs are real number fields.

Tests:
- 3 new cases in node-catalog.test.ts: 129.99999999999997 vs "130"
  is equal, 0 vs "" is not, "1.0" vs "1" is not.
- Counter-check: with the old rule (two real numbers only) exactly the
  "130" case fails. Original restored and compared with cmp.
- ./check.sh: 156 files, 2314 tests, CHECK EXIT 0 (before 2311).
