fix(sandbox): preserve array order in config hashing

 ### Fixes
 
 - Security: replace deprecated SHA-1 sandbox configuration hashing with SHA-256 for deterministic sandbox cache identity and recreation checks. Thanks @kexinoh.
+- Sandbox: preserve array order in config hashing so order-sensitive Docker/browser settings trigger container recreation correctly. Thanks @kexinoh.
 - Sandbox/Security: block dangerous sandbox Docker config (bind mounts, host networking, unconfined seccomp/apparmor) to prevent container escape via config injection. Thanks @aether-ai-agent.
 - Control UI: prevent stored XSS via assistant name/avatar by removing inline script injection, serving bootstrap config as JSON, and enforcing `script-src 'self'`. Thanks @Adam55A-code.
 - Discord: preserve channel session continuity when runtime payloads omit `message.channelId` by falling back to event/raw `channel_id` values for routing/session keys, so same-channel messages keep history across turns/restarts. Also align diagnostics so active Discord runs no longer appear as `sessionKey=unknown`. (#17622) Thanks @shakkernerd.
