Update NPM Packages

Updating NPM Packages

Read docs/development.md "Tracking Upstream Dependencies" section for full context.

Rules

• Dependencies are split into three groups:
  • dependencies — runtime packages bundled into the extension
  • devDependencies — build tools only (minimum for Azure DevOps pipeline)
  • optionalDependencies — lint, type-checking, and test tools (for development and GitHub Actions)
• Always use npm install --include=optional to get all three groups.
• The .npmrc uses an Azure Artifacts mirror; read its comments for authentication instructions.
• When updating engines.vscode follow the "Tracking Upstream Dependencies" section of docs/development.md.
• Update the ESLint packages (eslint, @eslint/js, typescript-eslint, eslint-config-prettier) together and fix any new lint warnings.
• After updating, verify: npm run compile, npm run lint, npm audit.
• For vulnerabilities in transitive dependencies identified by npm audit, add an overrides entry in package.json rather than using npm audit fix --force which may downgrade our packages.
• Check that each overrides entry is still necessary.
