v0.5.9

What's Changed

• Fixes Node 26 MCP discovery/tool-call timeouts by opting the CLI out of the optional MCP GET SSE stream.
• Adds Node-version CLI smoke coverage so --version stays network-free and Node 22/24/26 CLI behavior is checked in CI.
• Includes the recent upgrade documentation updates.

Validation

• Release tag points at origin/master with package.json and package-lock.json at 0.5.9.
• Publish workflow will run npm ci, npm run build, CLI smoke checks, npm pack --dry-run, and npm publish.
