fix: fix 7 failing tests (OCAS_DIR → OCAS_HOME + restore workflow destructure)

Root cause: tests used OCAS_DIR env var but store.ts reads OCAS_HOME,
causing tests to hit the global ~/.ocas vars instead of temp dirs.

- store-unified-threads.test.ts: OCAS_DIR → OCAS_HOME (3 tests)
- thread-resume.test.ts: OCAS_DIR → OCAS_HOME (3 tests)
- current-role.test.ts: restore { thread, workflow } destructure
  that was incorrectly removed by biome unsafe fix (1 test)

Result: 745 passed, 0 failed, 1 skipped

Closes #49
