Act as an expert compiler engineer and distributed systems architect. We are
developing a custom Node.js-based LPC Virtual Machine (GEM) that JIT-compiles
legacy LPC code into native JavaScript AST. We are replacing the legacy
UDP/TCP socket layer with a decentralized, zero-trust mesh networking stack
based on pub/sub, event sourcing, and Conflict-free Replicated Data Types
(CRDTs).

The Architecture:

The VM runs in complete isolation from the network. It communicates with the
Node.js host strictly via two in-memory arrays: rt.__INBOX and rt.__OUTBOX. 

LPC object properties are stored on a local _this context object within the
transpiled JavaScript.

The Objective:

Design a new networking module (efuns.d/10_mesh.js) containing the EFUN
mesh_sync_object(ob, topic, regex_pattern) and its counterpart
mesh_receive_distributed_objects(topic).

Technical Requirements:

The Proxy Interceptor: mesh_sync_object must dynamically wrap the LPC object's
_this context in a native JavaScript Proxy. 

Regex Filtering: The Proxy's set trap must intercept all variable assignments.
If the mutated property key matches the provided regex_pattern, it must push a
standardized JSON intent payload to rt.__OUTBOX. 

Echo Prevention: When the VM's tick processor unpacks external state changes
from rt.__INBOX, it must apply them to the LPC objects using Reflect.set to
bypass the Proxy traps and prevent infinite synchronization loops. 

State Reconciliation: Outline the Node.js host logic for resolving the
"chicken-and-egg" scenario: when a new node subscribes to a topic, how does it
request and ingest the authoritative state from the mesh before applying new
incoming events?

Please write the complete 10_mesh.js implementation and provide a brief
architectural breakdown of the host-side message dispatcher.
