问题描述 · Description

ZCode appears to load all projects into memory on startup or during use, rather than loading only the currently open project. This results in unnecessarily high resource consumption, as confirmed by Resource Manager, and scales poorly for users with multiple projects.

The application loads all projects into memory instead of limiting loading to the currently open project, leading to high resource usage.

Impact

Unnecessary memory/CPU usage that scales with the number of projects rather than the number of open projects — this can slow down the system, especially for users with many projects, and may lead to degraded performance or crashes on lower-resource machines.

复现步骤 · Steps to reproduce

1. Have multiple projects available (not all open).
2. Open only one project in ZCode.
3. Open Resource Manager (or equivalent system monitor).
4. Observe memory/resource usage is high, consistent with all projects being loaded rather than just the open one.
5. See attached screenshot for reference.

期望表现 · Expected behavior

Only the currently open project should be loaded into memory. Other (non-open) projects should not consume system resources until they are actually opened.

实际表现 · Actual behavior

All projects are loaded into memory regardless of whether they are open, resulting in significantly higher-than-expected resource consumption (as shown in the attached Resource Manager screenshot).

No source file, test, or entry point is identified. Reproduce the issue on Windows 11 with multiple projects, compare resource usage with one project open, and trace when unopened projects are loaded. Done means unopened projects no longer consume resources until opened, with the behavior verified through a resource monitor.
