chore: resolve merge conflict in sdk-runner.ts

Merged both native session resume logic and system prompt additions:
- Keep claudeSessionId/forkSession for native SDK session resume
- Keep buildSystemPromptAdditionsFromParams for Moltbot context injection
- History suffix now conditional on native resume mode
