VS Code extension: CoreBall Explorer (token-budget slider)

[francomano]

Problem

Developers use CoreBall via CLI, but ideal UX is in-editor: task + token-budget slider + live preview.

Proposal

Minimal VS Code extension (vscode-coreball):

• Command: “CoreBall: Pack context for task”
• Webview with task input + token slider (128-8192) + Markdown preview
• Calls bundled coreball pack --format json (or HTTP API if coreball serve running)
• Publish to VS Code Marketplace + Open VSX

Benefits

• VS Code Marketplace drives discovery, stars and PRs
• Trending keywords: vscode, extension, ai, context-engineering

Acceptance criteria

• vscode-coreball/ with package.json, onCommand:coreball.pack
• Shows pack results in webview
• Published to Marketplace + Open VSX
