V0.8.4

• Improve: raise the sandbox proxy's response-header timeout from 35s to 5 minutes to fit AI/agent workloads, where time-to-first-byte can be much longer than a typical web backend (long tool-call loops, slow model TTFT under load). This previously surfaced as spurious net/http: timeout awaiting response headers errors; only affects the wait for headers, not streaming/SSE response bodies.
• Fix: process snapshot being cleared to empty when fetching processes fails.
• Improve: automated build now injects the version via -ldflags instead of a hardcoded version string.
