[brandonroberts]

Goal

Polish, configuration, and performance for a stable 1.0 release.

Features

• Extension settings — User-configurable options to enable/disable individual feature areas (route completions, API route index, etc.)
• Performance — File watchers for incremental route index updates, debounced operations
• Status bar item — Show detected Analog project info (version, SSR mode, route count)

Key files

• packages/vscode/package.json — contributes.configuration section
• packages/vscode/src/extension.ts — status bar, settings handling

Depends on #9
