release: bump 0.9.8 -> 0.9.9 (#351)

* release: bump 0.9.8 -> 0.9.9

* ci(lychee): exclude the CHANGELOG version-compare links

The CHANGELOG compare URLs point at the release tag created *after* the bump is
merged; ci.yml runs on push/PR (never on the tag), so the tag never exists when
lychee runs and 'compare/vX...vY' / 'compare/vY...HEAD' 404. Excluded by the same
pattern mechanism already used for the crates.io / npm package URLs — one pattern
covers every future version, no per-release change needed.
