Module marker 

.yuilink marker file detection + parsing.

Two forms are accepted:

• empty file → “junction this dir at the parent mount’s dst” (the original presence-only marker semantics)
• TOML with [[link]] entries → “junction this dir at each entry’s dst, when filtered” — overrides the parent mount’s dst.

# $DOTFILES/home/.config/nvim/.yuilink
[[link]]
dst = "{{ env(name='HOME') }}/.config/nvim"

[[link]]
dst = "{{ env(name='LOCALAPPDATA') }}/nvim"
when = "{{ yui.os == 'windows' }}"
