Update mise tools

Bump lychee 0.23.0 -> 0.24.2 and ruby 4.0.3 -> 4.0.6 via `mise up`.

lychee 0.24 replaced the boolean `include_fragments` config key with
a `FragmentMode` string (none/anchor-only/text-only/full). Migrate
lychee.toml to `include_fragments = "anchor-only"` to preserve the
existing anchor-fragment checking behavior without opting into the
new text-fragment (`#:~:text=`) checking.
