chore: fix .gitignore glob to cover nested reports directories

[divinemike019]

Summary

The root .gitignore's reports/*.json rule only matched the top-level ./reports/ path. Any nested reports/ directory (e.g. src/audit-guard/reports/) was not covered, causing src/audit-guard/reports/latest-scan.json to be tracked in version control unintentionally.

Changes

• .gitignore: Changed reports/*.json → **/reports/*.json so the glob matches report JSON files at any directory depth.
• src/audit-guard/reports/latest-scan.json: Removed from git tracking via git rm --cached. The file remains on disk but is now correctly ignored.

Verification

$ git ls-files | grep reports
reports/.gitkeep          ← intentional (kept by !reports/.gitkeep rule)

$ git check-ignore -v src/audit-guard/reports/latest-scan.json
.gitignore:4:**/reports/*.json   src/audit-guard/reports/latest-scan.json

Closes #312

Correction on my earlier "please ensure all checks pass" comment — that wasn't your PR's fault. The RPC Relayer Bridge Tests job was failing on main itself, so every open PR here inherited a red check.

Cause was on our side: #327 bumped axios to 1.x (which made headers required on a config type used in a test mock) and #321 left a duplicate variable declaration behind. Neither surfaced until #323 wired those tests into CI for the first time. Fixed in #332, now merged.

I've updated your branch so it picks up the fix — CI is re-running. Apologies for the noise.
