Bump the version to 0.99 and require collocatordb 1.8.0
The explanations added for LD, LDaf and the effective window size only
hold with collocatordb 1.8.0, where Log-Dice follows Rychly's
definition. Built against an older one, the interface would show the
previous LD values under the new text, without anything indicating the
mismatch, so the minimum version is raised from 1.5.0.

# Changelog
+## [0.99] - 2026-09-04
+
+- requires collocatordb 1.8.0, in which Log-Dice is computed as Rychlý (2008)
+ defines it, without the window size factor that used to be applied to the
+ frequency of the node. LD values are higher than before, by up to the binary
+ logarithm of the window size, and comparable to those of other tools such as
+ Sketch Engine. Building against an older collocatordb would show the previous
+ values under the new explanations, which is why the minimum version is
+ enforced
+- LDaf and the order of the collocates are unchanged. It is the auto focus
+ score, not Log-Dice of the auto focus window, and its denominator grows with
+ the width of the selected window, which is what makes it sensitive to how
+ concentrated a pair is. Its tooltip gives the formula and notes that it is
+ therefore not on the same scale as LD
+- the info tab explains that LL, MI, MI², MI³ and nPMI are computed over the
+ attested positions, i.e. those in which the collocate occurs at least once,
+ rather than over the whole context window, and that their values are
+ therefore not directly comparable to those of tools computing with a fixed
+ window size. The term auto focus is reserved for the selection of positions
+ that yields the highest score, as Belica coined it for the CCDB
+
