Version 1.2 (#35)

* sdb: support sorted iteration and efficient seeking (#33)

- Implement shard‑aware traversal so Items() yields keys in deterministic
lexical order (ascending by default) or reverse order when sdb.Desc is
passed.

- Items() now accepts a start key, enabling seeks without
scanning earlier shards. A binary search on the in‑memory shard table picks
the first candidate shard.

- Fix `bolt` and `bbolt` drivers `seek()` function.

* sdb: add filesystem interface (#34)

* Encapsulate os.* calls in `fileSystem` abstraction

- Encapsulate os.* calls in `fileSystem` abstraction
- Create tests with a mocked FS
- Split `Put` tests into `Put` and `Put_Concurrent`
- Create `TestConcurrentOperations`
- Create `metadataStore`
- Add DB.syncInterval field

* Fix cache stats race

* shelve-cli: support descending iteration

driver: update to `v1.2.0` (#36)

Version 1.1 (#29)

* Create `go-shelve` CLI (#27)

* cmd: add basic command-line functionality

* shelve: change the default codec to json

### Why JSON?
- Human-readable and easy to debug
- Works seamlessly with the shelve-cmd CLI
- Interoperable with other tools and languages
- Ideal for simple data (structs, strings, numbers, slices, maps)

Gob codec can still be used for full Go fidelity with:

```Go
db, _ := shelve.Open("mydb", shelve.WithCodec(shelve.GobCodec))
```

* shelve: update README.md

* shelve: improve string codec and remove Gob fallback

- Extended stringCodec to support booleans, floats, and fixed-size byte arrays ([N]byte).

- Added support for types implementing encoding.TextMarshaler / TextUnmarshaler.

- Removed Gob as a fallback for unsupported key types — unsupported types must now be explicitly configured.

* shelve: run go.yml in dev / refactor main.go type alias

* shelve: rename `StringCodec` to `TextCodec` (#28)
