Bind mlx_contiguous and _mlx_array_is_row_contiguous from mlx-c.
Floats(), DataInt32(), and Ints() now automatically handle non-contiguous
arrays (from Transpose, BroadcastTo, SliceAxis, etc.) by checking
IsRowContiguous() and making a contiguous copy when needed.
Previously these methods returned silently wrong data for view arrays.
The old workaround of Reshape(arr, totalSize) is no longer needed.
7 new tests for contiguous handling (transpose, broadcast, slice views).

Replace local TextModel, Backend, Token, Message, and option types with
forge.lthn.ai/core/go-inference. go-mlx is now a pure backend that
registers "metal" into the shared inference registry via init().
Deleted: textmodel.go, options.go, backend.go
Updated: register_metal.go (implements inference.Backend with Available()),
mlx_test.go (uses inference.* types, 4 new tests), go.mod,
internal/metal/generate.go (added RepeatPenalty)
159 tests passing (148 internal/metal + 11 root).

Move foundation CGO files from root package to internal/metal/ package.
Changes package declaration from `package mlx` to `package metal`.
Updates CGO SRCDIR paths to account for new location (two levels deeper).
Extracts go:generate directives into root generate.go.
