like `Find.find(query)` explore `Find.unfind(URI)`, to "decode" a URL into a "Find syntax"

For example, in the case of `https://github.com/internet4000/find` and pseudo code:
```txt
const my_url = "https://github.com/internet4000/find"
const result = Find.unfind(my_url)
console.log(unfind)
{
input: "https://github.com/internet4000/find",
matches: [
{
exact: true,
output: "https://github.com/internet4000/find",
query: "&ghi4k find"
},
{
exact: true,
output: "https://github.com/internet4000/find",
query: "&gh internet4000 find"
},
{
exact: false,
output: "https://github.com/internet4000/find/issues",
query: "*ghi_i4_find" // could be `*` a bookmark symbol, like firefox
},
[...]
]
}
```

Could test matching symbol.engines URLs from the domain, and their path, and figure if there are matching symbols to build such a resulting URL.
