What
A large mechanical refactor turned dozens of module-level variables into fields on lazily created singleton objects reached through accessors, some with an explicit reset(). Nothing changes for you, but it makes tearing down and restarting a session inside a running process possible.
Details
Covers the command fuzzy-search index, shell history, sandbox session flags, artifact and workshop state, plugin and marketplace caches, MCP tool-refresh sequences, terminal layout caching (a per-node cached layout instead of a WeakMap) and several event emitters.
The sandbox reset is async and calls the settings-subscription cleanup.
