apiplan v0.2.2 — test portability fix

Patch release. No product changes.

Verifying the v0.2.1 tag from a fresh clone (rather than the tree it was built in) surfaced 2 of 87 tests failing there while passing locally: on macOS /var is a symlink to /private/var, so the installer's pwd and the test's import.meta.dir spell the same directory differently. The assertion now compares resolved paths.

Verified 87/87 in place and from a copy under /tmp, which is where the old assertion broke.
