[misc/gnoview] context & next steps for the gno package viewer

[zivkovicmilos]

Description

Previously, gno used to utilize a package / realm viewer called gnoview that relied on the logos browser.
gnoview has since been deprecated and removed with this PR.

gnoview was initially introduced in commit 38f8e81.

This issue aims to start a discussion about implementing a similar package viewer to gnoview.

Example realm:

// gno.land/r/main
package main

var root Node

type Node interface{}
type Key interface{}
type Value interface{}

type InnerNode struct {
	Key   Key
	Left  Node `gno:owned`
	Right Node `gno:owned`
}

type LeafNode struct {
	Key   Key
	Value Value
}

func init() {
	root = InnerNode{
		Key: "old",
	}
}

func main() {
	println("gno.land initializing...")
	node1 := LeafNode{
		Key:   "left",
		Value: "left value",
	}
	node2 := LeafNode{
		Key:   "right",
		Value: "right value",
	}
	root = InnerNode{
		Key:   "new",
		Left:  node1,
		Right: node2,
	}
	println("gno.land ready!")
}

View of this realm using gnoview, that outlines the different types (structs, methods, interfaces) present in the realm:

Current state: not a priority.

This issue can be used to discuss the idea and share links to related resources.

Next step: to create a CLI alternative. Within gnodev?

Next step: to create a CLI alternative. Within gnodev?

What kind of information should the alternative display about the package? The same info logos used to?
