fix(tests): canonicalize the temp repo path in the integration helper (#200)

setup_integration_repo took its path straight from mktemp -d, which on macOS returns /var/folders/... while /var is a symlink to /private/var. git canonicalizes when it registers a worktree, so the preRemove hook received the /private/var spelling and 'cmd_clean --merged uses nested registered worktree path' compared it against the /var one.

This is the test's expectation being wrong rather than a product bug: passing a /var path to 'git worktree add' makes git itself register the resolved one.

Resolving the path once in the helper fixes it for every integration test. Linux is unaffected, since mktemp -d returns /tmp with no symlink, which is why CI stayed green.

Local suite now passes 561/561, previously 560/561.

+- The integration test helper now canonicalizes its temporary repository path. On macOS `mktemp -d` returns a `/var` path while git records the resolved `/private/var` one, so `cmd_clean --merged uses nested registered worktree path` compared two spellings of the same directory and failed locally while passing in CI.
