test(skill): install linker asserts harness-home link topology

Browse Source 
The two install-linker-compatibility tests still asserted the pre-isolation
behavior (mosaic skill links planted in $HOME/.claude/skills). This branch
deliberately moved the link farm into the mosaic-owned harness homes
($MOSAIC_HOME/.claude/skills) and demoted the base-install dirs to
cleanup-only legacy targets, so the tests now assert the new topology:
the skill links appear under the harness home, foreign links in the legacy
dir are preserved, and no new mosaic link is planted in the base install.
