v2.5.2

Welcome to v2.5.2: a patch that unbreaks all Cloudflare-sent email, plus a boot fix for self-hosted MCP.

What's Changed

🐛 Bug fixes

• Fixed all Cloudflare-sent email failing with HTTP 400 (email.invalid): callers set the platform-controlled Message-ID header, which Cloudflare rejects on the whole request. Tracking now travels in an allowed X-Spliit-Delivery-Id header, display-name senders use the documented {address, name} shape, and permanent bounces no longer record phantom sends (9cab732b by @antonio-ivanovski)
• Fixed the MCP server failing to boot when OPENAI_APPS_CHALLENGE is set but empty (as compose ${VAR:-} interpolation produces); empty values now count as unset (cff430fe by @antonio-ivanovski)
