#8800: chore: apply oxfmt formatting

<!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR applies `oxfmt` formatting changes, including: - `package.json`: reorders entries in the published `files` array (no functional content changes beyond ordering). - `CLAUDE.md`: updates the single-line `AGENTS.md` pointer and adds a trailing newline. These are formatting/metadata-only adjustments intended to keep repository files consistent with the configured formatter. <h3>Confidence Score: 4/5</h3> - This PR is likely safe to merge and appears formatting-only, with one caveat around symlink preservation for CLAUDE.md. - The only behavioral surface area is metadata: `package.json` ordering should not change published contents, but `CLAUDE.md` is/was a symlink and changing it via formatting tools can accidentally convert it into a regular file depending on contributor tooling/patch application. - CLAUDE.md (symlink vs regular file handling); package.json (published files list ordering) <!-- greptile_other_comments_section --> _{(3/5) Reply to the agent's comments like "Can you suggest a fix for this @greptileai?" or ask follow-up questions!} <!-- /greptile_comment -->
