refactor(store): extract @uncaged/nerve-store from daemon (#85)

- Create packages/store/ with log-store, log-archive, blob-store (~900 LOC)
- daemon depends on @uncaged/nerve-store (workspace:*)
- CLI depends on @uncaged/nerve-store, delete daemon-types.ts
- Move store-related tests to packages/store/src/__tests__/
- All store tests pass (73/73), no new regressions
