The seedTestRepo fixture matched store repo/worktree paths against the seeded
realpath with strict string equality, which fails on Windows when main's
canonicalized path differs in separators or drive-letter case — every spec
then dies at "Expected e2e repo to be loaded" before its own assertions
(observed on a real Windows validation run of this branch). Compare through
shared/cross-platform-path's normalizeRuntimePathForComparison instead,
matching node-side so the shared helper is used verbatim.
