fix: upgrade hono to ^4.12.18 to address CVE-2026-44456

[brendan-kellam]

Fixes SOU-1069

Summary

Updated the hono package resolution from ^4.12.14 to ^4.12.18 to address CVE-2026-44456, a bodyLimit() bypass vulnerability for chunked/unknown-length requests.

Details

• CVE: CVE-2026-44456
• Affected package: hono v4.12.14 (transitive dependency via @modelcontextprotocol/sdk)
• Fixed in: hono v4.12.18
• Vulnerability: bodyLimit() does not reliably enforce maxSize for requests without a usable Content-Length header (e.g., Transfer-Encoding: chunked), allowing oversized requests to bypass the limit and reach handler logic

Changes

• Updated @modelcontextprotocol/sdk/hono resolution in package.json from ^4.12.14 to ^4.12.18
• Regenerated yarn.lock to apply the resolution

Testing

• All existing tests pass (789 tests across all packages)
• Verified the upgraded version with yarn why hono --recursive

Linear Issue: SOU-1069
