out of bounds on IPC Stream

[blaginin]

Issue Description

I have an web endpoint for which you POST-stream vortex array. Right now, if you send large enough (to force chunking?) it fails with

Failed to read array: Range [0, 4) is out of bounds.

Expected Behavior

I should be able to read the array

Actual Behavior

Error is returned

Reproduction Steps

I believe this illustrates the bug: develop...db/failing-stream

right now it fails with

called `Result::unwrap()` on an `Err` value: Range [5120, 5124) is out of bounds.

OS Version Information

MacOS 26.1 (25B78)

I acknowledge that:

• I have searched the Vortex repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.
