[None][chore] promote PrimTS source from TRT-LLM #18815

[yuxianq]

Dev Engineer Review

The change updates only the flashinfer-prims-ts source URL. The pinned revision, branch, patch, and digests remain unchanged. No runtime, API, dependency, or kernel behavior changes are included.

QA Engineer Review

No test changes.

Per-File QA Perspective

• 3rdparty/vendor_sources.lock.yaml: Verify that materialization from the new repository URL produces the same pinned source, vendor files, patch, and digests.

Description

Promote the exact source revision reviewed in #18815.
Only the PrimTS lock URL/branch changes. The source SHA, selected vendor files, compatibility patch, and digests are unchanged.

Test Coverage

Source materialization and lock-only diff verified by the promotion tool. No new kernel behavior. The tool posts /bot skip --comment "skip CI since no code change" to request the bot's no-code-change CI path. Automatic GitHub checks and required reviews still apply.

PR Checklist

• No runtime/API/dependency changes.
• Immutable source pin and vendor content preserved.
• Please check this after reviewing the above items as appropriate for this PR.

Required squash commit message

Preserve the following message, including the provenance block and DCO sign-off.
