integration: VS Code extension for inline scoring + one-click humanize

[devswha]

Why it matters

VS Code (and Cursor) is the largest editor base globally. Inline score + AI-suspicious squigglies is exactly the kind of thing reviewers screenshot for X.

Acceptance criteria

• New repo devswha/patina-vscode
• Status bar item showing current file's score (debounced background patina --score)
• Diagnostics on AI-suspicious sentences (from --audit)
• Command Patina: Humanize Selection shells out to CLI with diff-preview confirm
• Settings: patina.cliPath (default npx patina-cli), patina.language, patina.backend, patina.scoreThreshold
• Hard scope cut for v1: no embedded LLM, no API key prompts — shells out to CLI only
• Depends on npm-publish

Wave 4 triage: this stays open.

Concrete blocker: a VS Code extension belongs in a dedicated extension package/repo with marketplace packaging, command UX, and editor security review. The current campaign only added static-site integration examples inside this repo; it did not create or publish devswha/patina-vscode.
