Summary

• Adds a global --read-only flag for CLI request commands.
• Allows GET, HEAD, and OPTIONS while blocking mutating methods before request setup.
• Carries the flag through config and covers allowed and blocked paths with tests.

Validation

• go test -v -short ./src/...
• go build ./src/cmd/rest
• golangci-lint run --timeout=5m --new-from-rev origin/main ./src/...
