feat: Add warning about NaN invariant and -0.0 for direct comparisons

[MaxGraey]

Produce warning like:

WARNING AS907: 'NaN' does not compare equal to any other value including itself. Use isNaN(x) instead.
      :
    2 │ assert(x != NaN);
      │        ~~~~~~~~
      └─ in index.ts(2,8)

and

WARNING AS907: 'NaN' does not compare equal to any other value including itself. Use isNaN(x) instead.
      :
    3 │ assert(x == NaN);
      │        ~~~~~~~~
      └─ in index.ts(3,8)

also

WARNING AS908: Comparison with -0.0 is sign insensitive. Use Object.is(x, -0.0) if the sign matters.
      :
    4 │ assert(x != -0.0);
      │        ~~~~~~~~~
      └─ in index.ts(4,8)
