🟡 Changes recommended

Missing boundary checks allow region operations to access neighboring data, and unsupported index-region schemas can cause runtime failures.

What changed in this PR

Adds typed buffer regions to TypeGPU, allowing parts of one buffer to be read, written, bound, and used independently for rendering or compute operations.

Changes:

• Introduces region creation, byte-range operations, bindings, unwrapping, and serialization.
• Integrates regions with vertex, index, and indirect commands.
• Adds tests, API documentation, and an indirect-culling example.

ℹ️ Minor suggestions only — two region boundary contracts worth a look. The core offset plumbing (region write/patch/clear/copyFrom/read offsets, bind-group sizing, vertex/index/indirect element→byte math) checks out; comments inline.

Reviewed changes

• buffer.region(schema, accessor | { offsetBytes }) (core/buffer/bufferRegion.ts) — new TgpuBufferRegion API with accessor navigation (fitsElement accepts schema-equal elements, array prefixes and array runs) and raw { offsetBytes } ranges, plus offset/fit validation.
• Offset-aware buffer IO (buffer.ts, dataIO.ts, partialIO.ts, offsetUtils.ts) — write/patch/clear/copyFrom/read refactored onto offset-carrying internals; typed arrays accepted as raw bytes; getPatchInstructions/readFromArrayBuffer gain a base offset; navigateSchema reports the reached schema and array run.
• Region binding (bufferRegion.ts bufferBindingOf, tgpuBindGroupLayout.ts, init.ts) — regions bind with offset/size and device-limit alignment validation; root.unwrap(region) yields a GPUBufferBinding.
• Region as vertex/index/indirect buffer (drawState.ts rawRegionOf, pipelineUtils.ts resolveIndirect, renderPipeline.ts) — offsets count from the region start.
• Supporting types and integration — BindableBuffer, TgpuMutable/TgpuReadonly/TgpuUniform genericized over the bound buffer, isBufferRegion, serial restore and exports.
• Docs, example, tests — buffer-regions section in buffers.mdx, new rendering/indirect-culling example, tests/bufferRegion.test.ts, and updates to tests/buffer.test.ts/tests/serial.test.ts.

Reviewed changes

The only content change to any PR file since the prior pullfrog review (33a8617) is documentation. The branch was rebased onto a rewritten base tip and re-recorded, but every source, test, and example blob is byte-identical to the previously-reviewed revision (confirmed via matching git ls-tree blob hashes); the one non-doc difference, .../apis/buffer-views.mdx, belongs to the rewritten base branch, not this PR.

• root.unwrap(region) contract documented (apps/typegpu-docs/src/content/docs/apis/buffers.mdx) — the region section now states the returned GPUBufferBinding carries the region's exact buffer/offset/size, and that unlike root.createBindGroup it neither rounds the size up to 4 bytes nor checks the offset alignment.

That wording matches the code at packages/typegpu/src/core/root/init.ts:589 (return { buffer: buffer.buffer, offset, size: resource.size }), which performs no rounding or alignment validation — versus bufferBindingOf, which does both. Both prior review threads (init.ts:589, pipelineUtils.ts:99) are resolved: the first by documenting the raw escape-hatch contract, the second by the author's deliberate "regions trust the caller" decision.
