Clarify multipart collection release notes

[tim-smart]

Summary

• clarify the multipart changeset to cover both the new Channel.mkUint8Array API and the File.contentEffect quadratic-buffering fix
• record the measured approximately 90x improvement for collecting a 16 MiB chunked upload
• document the emitted-buffer retention requirement on Stream.mkUint8Array and Stream.mkArrayBuffer

Validation

• pnpm check
• Stream doctests (227/227)
• dprint and oxlint on changed files
• changeset status --since origin/main

Closes EFF-573

Reviewed changes — Reviewed the full diff of this docs-and-changeset clarification against the Channel.mkUint8Array implementation and the multipart collection path it documents.

• Changeset rewording — The multipart-collect-linear.md note now names both the new Channel.mkUint8Array API and the File.contentEffect quadratic-buffering fix (~90x on a 16 MiB chunked upload). I confirmed this is grounded: the pre-#7157 collectUint8Array re-allocated and copied the full accumulator on every pull (the quadratic path FileImpl.contentEffect used), and the 16 MiB / 64 KiB chunked scenario is the case exercised by packages/effect/benchmark/http/multipart.ts.
• Stream.mkUint8Array / Stream.mkArrayBuffer **Gotchas** — New JSDoc documenting full in-memory materialization and that the source must not reuse or mutate emitted buffers. Accurate: Channel.mkUint8Array accumulates buffer references via runFold and copies into the result only after the channel completes (Channel.ts:7993), so emitted buffers are in fact retained until collection completes.
