…essor

The generated entry named the right crate this time — scoping the pull
request title to `fix(ddx-core)` was enough for that — but it was one
line for a silently-wrong result, and it omitted the release's added API
entirely.

The fix now states the three-valued-logic reason a NULL row fell into
`ELSE`, who is affected (anyone differentiating `abs` over data with
gaps, on any engine), why it is worth upgrading for even without a
visible symptom, and the before/after of the emitted CASE. Also records
the DuckDB DECIMAL typing that the same branch fixes.

`Ddx::unary_rule_names()` gets an Added entry naming 0.2.1 as its floor,
since a caller writing `ddx-core = "0.2"` can otherwise resolve 0.2.0 and
fail to compile against it.
