build(deps): bump undici from 6.28.0 to 6.28.1

[dependabot]

Bumps undici from 6.28.0 to 6.28.1.

Release notes

Sourced from undici's releases.

v6.28.1

⚠️ Security fixes

High severity

• GHSA-rfgv-xxqx-mfg5: a WebSocket server could select a subprotocol when none was requested, causing an uncaught TypeError that could terminate the process. Undici now rejects the handshake with protocol error 1002. Fixed by 2af0faf8.

Medium severity

• GHSA-3wwx-pv8p-q78v: a malformed permessage-deflate payload exceeding the configured decompression limit could emit an unhandled zlib error and terminate the process. Undici now destroys the inflater after reaching the limit. Fixed by 07c60d9c.

Low severity

• GHSA-r53p-7pc4-xj5r: the retry interceptor could concatenate a resumed response with inconsistent framing into downstream output, enabling response splitting or corruption. Undici now validates Content-Range against the original response framing before resuming. Fixed by ce31bc82.

What's Changed

• [v6.x] perf(h1): drop idle-socket timer floor with a ref'd setImmediate (#5707) by @​mcollina in nodejs/undici#5770

[claude]

LGTM, straightforward dependency version bump.
What was reviewed: the only change is yarn.lock updating "undici@ npm:^6.25.0" resolution from 6.28.0 to 6.28.1 (version, resolution string, checksum) — matches the dependabot patch-release bump description; no application source or config files changed.

Extended reasoning...

The diff touches only yarn.lock, bumping the pinned "undici" resolution from 6.28.0 to 6.28.1 (version, resolution, checksum), consistent with the dependabot PR description for a patch security release. No application code, auth, or crypto paths are touched. This is a small, mechanical, auto-generated lockfile change with no ambiguity, so it is safe to approve without further human review.
