Environment-Specific OAuth Credentials

What: Separate OAuth credential storage for local development vs production

How to use:

# Production credentials (default)
# Stored in: ~/.claude.json

# Local development credentials
export USE_LOCAL_OAUTH=1
# Stored in: ~/.claude-local-oauth.json

Details:

• Prevents accidentally overwriting production OAuth tokens during development
• Separate keychain entries: "Claude Code" vs "Claude Code-local-oauth"
• Configuration files: .claude.json (prod) or .claude-local-oauth.json (local)
• Infrastructure for staging environment included but not yet active
