Single env var NETWORK=corp|home controls all proxy config.
Source from ~/.zshrc — sets http_proxy, NPM_CONFIG_REGISTRY,
PIP_TRUSTED_HOST, NODE_TLS_REJECT_UNAUTHORIZED automatically.
No more ~/.npmrc rewriting.
- Replace hardcoded /Users/sd9235/ paths with $HOME in all SKILLS docs
- Use WORKSPACE_DIR variable in backup-main.sh (auto-resolves from script location)
- Genericize 'Forcepoint CertChecker' / 'corporate proxy' to 'SSL-intercepting proxy'
- Add scripts/switch-network.sh for toggling npm between corporate proxy and home
- No functional code changes — only comments, docs, and paths
