feat(footer): hover-glow links to lyxlimo + karleksguiden (#25)

MainLayout footer now includes attribution: 'Crafting digital
experiences for lyxlimo.se & karleksguiden.se' visible on all pages.

On index page only: hovering lyxlimo.se tints hero-logo with
green (#4fd1c5 teal), hovering karleksguiden.se tints with
magenta (#c026d3). Mouseleave restores default white smoky-path
animation. Mechanism reuses existing data-logo-tint attribute on
#text-wrapper.

Removed logo-pulse functionality entirely (threadLogoIn/Out paths,
runLogoPulse function, LOGO_PROBABILITY, updateLogoThreadPaths,
resize/scroll listeners for logo threads). Hover-based UX replaces
the random pulse approach per Linus design preference.
