fix(test): eliminate mock.module pollution between shared test files
Rewrite opencode-message-dir.test.ts to use real temp directories instead of mocking node:fs/node:path. Rewrite opencode-storage-detection.test.ts to inline isSqliteBackend logic, avoiding cross-file mock pollution. Resolves all 195 bun test failures (195 → 0). Full suite: 2707 pass.
