chore: style use · instead of . for lambda dot notation
...
We are considering removing `.` as an alternative for `·` in the
lambda dot notation (e.g., `(·+·)`).
Reasons:
- `.` is not a perfect replacement for `·` (e.g., `(·.insert ·)`)
- `.` is too overloaded: `(f.x)` and `(f .x)` and `(f . x)`. We want to keep the first two.

fix: bug at addSmartUnfoldingDef
...
The approach using `matcherBelowDep : NameSet` was not correct because
we "reuse" matcher-declarations. For example, in the definition
```
def f : Nat → Bool
| 0 => true
| n + 1 => (match n with
| 0 => true
| _ + 1 => true) && f n
```
we have to `match`-expressions but they can be compiled the same
matcher `f.match_1`. Thus, the set `matcherBelowDep` would contain
`f.match_1` since the first occurence refined the `Nat.below` argument
at `mkBRecOn`. Thus, `addSmartUnfoldingDef` was incorrectly assuming the second
`match` was refined too.
We fixed this issue by simulating `mkBRecOn` behavior.
fixes #445
