fix(heartbeat): evitar versoes desnecessarias comparando dados antes de atualizar

Browse source 
- Compara inventory/metrics com valores atuais antes de incluir no patch
- Usa JSON.stringify para comparacao eficiente de objetos
- Filtra campos de metadata que realmente mudaram
- Evita criacao de versoes quando heartbeat envia dados identicos

Isso previne o acumulo de versoes no Convex que causava OOM.

Reducao de memoria apos limpeza manual:
- DB: 450MB -> 16MB (96%)
- RAM: 7GB -> 189MB (97%)
