Adds a pnpm override pinning postcss to ^8.5.18, the first version patched against both GHSA-r28c-9q8g-f849 (path traversal via previous sourceMappingURL auto-loading, fixed in 8.5.18) and GHSA-6g55-p6wh-862q (arbitrary file read via attacker-controlled sourceMappingURL in CSS comments, fixed in 8.5.12). postcss is a transitive dependency of vite (devDependency); resolved version is now 8.5.22. Verified: pnpm build and pnpm test pass with no regressions.

Dependabot alert #51 flagged that this PR's postcss override (^8.5.18, resolving to 8.5.22) is still within the vulnerable range for an incomplete-fix follow-up to the sourceMappingURL disclosure advisory (Medium). Upstream fully patched it in 8.5.23; bump the pnpm override to close the remaining exposure.
