+Add a synchronous codec pipeline (`CodecChain`) used for whole-chunk reads and writes when every codec in the pipeline implements `SupportsSyncCodec`, avoiding per-chunk async dispatch overhead. The `SupportsSyncCodec` protocol is now generic over its decoded and encoded buffer types, matching `BaseCodec`.

+Skip the read-before-write step when a write covers an entire shard, eliminating an unnecessary `get` on full-shard overwrites with the sharding codec.

+Rename the `DimensionNames` type to `DimensionNamesLike` to reflect that it models the wide input type that is narrowed to the `dimension_names` attribute on V3 array metadata, matching the `XLike` naming convention used by other input-narrowing types.

+Fix handling of `NaT` default fill values for `datetime64` and `timedelta64` data types. Equality checks now use `numpy.isnat` so that the default fill value compares correctly against `NaT`.
