Web Content Fetching

Fetch web content in this order:

1. Prefer markdown-native endpoints (content-type: text/markdown)
2. Use selector-based HTML extraction for known sites
3. Use the bundled Bun fallback script when selectors fail

Prerequisites

Verify required tools before extracting:

command -v curl >/dev/null || echo "curl is required"
command -v html2markdown >/dev/null || echo "html2markdown is required for HTML extraction"
command -v bun >/dev/null || echo "bun is required for fetch.ts fallback"

Install Bun dependencies for the bundled script:
