Inter-Sandbox Networking & Large Commands

This release improves sandbox infrastructure with configurable inter-sandbox networking. The new INTER_SANDBOX_NETWORK_ENABLED environment variable controls whether Docker sandboxes can communicate via a custom bridge network, defaulting to enabled.

Large command execution now works correctly for exec and code_run operations. Previously, commands were passed as process arguments and could hit the kernel's ARG_MAX limit. Commands are now piped via stdin to the shell process, removing the size constraint entirely and fixing a long-standing limitation for large payloads.

The dashboard gains react-query-based audit log views and PostHog tracking for the command palette. Documentation expands with organizations references and signed preview URL token expiry details.
