CLI database commands fail with "db.load is not a function" (v0.2.26)

[vincenthsin]

Bug Report

CLI Version: 0.2.26
Node.js: v20.20.2
Platform: WSL (Ubuntu 24.04)

Problem

All CLI commands that open an existing database fail with:
✖ Failed to load database
db.load is not a function

Affected commands: stats, search, insert, export, import

Steps to Reproduce

1. Run the demo to create a database:
   npx ruvector demo --basic
2. Try to use the database:
   npx ruvector stats ./demo.db
   npx ruvector search ./demo.db --vector "[0.8, 0.6, 0, 0]"
   npx ruvector export ./demo.db -o out.json

All fail with "db.load is not a function"

What Works

• npx ruvector demo --basic works (uses internal code path)

• The Node.js API works correctly:

  const { VectorDB } = require('ruvector');
  const db = new VectorDB({ dimensions: 4, storagePath: './test.db' });
  await db.insert({ vector: [1,0,0,0], metadata: { label: 'x-axis' } });
  const results = await db.search({ vector: [0.8,0.6,0,0], k: 3 });

• npx ruvector doctor reports all checks passing

Conclusion

The native bindings work correctly via the JS API. The CLI's database
load path appears to be calling a method that doesn't exist on the
VectorDB instance.
