P1: Unreviewable 258k-line compiled artifact added unrelated to provider PR

Added 258k-line .cjs file with no reviewable diff, unrelated to the PR purpose.

Remove accidental commit or verify via reproducible build; inspect locally for hidden payloads.

<file name="dist/burst-100k.cjs">
<violation number="1" location="dist/burst-100k.cjs">
<priority>P1</priority>
<title>Unreviewable 258k-line compiled artifact added unrelated to provider PR</title>
<evidence>A new file dist/burst-100k.cjs with 258,278 additions was added, but the patch content is empty so reviewers cannot inspect it. The filename suggests executable CommonJS code, yet it appears completely unrelated to the stated goal of staging a Northflank sandbox provider.</evidence>
<recommendation>Remove the file if it was committed accidentally. If it is a required artifact, ensure it is produced by a reproducible build in CI rather than committed directly. Before merging, inspect the file locally for obfuscated code, embedded secrets, or unexpected network requests.</recommendation>
