Add CODEOWNERS file

[luisschwab]

GitHub allows us to add a .github/CODEOWNERS file specifying "owners" of certain parts of the codebase. When a PR touches those files, the "owners" get an automatic review request.

See an example here: https://github.com/bitcoindevkit/bdk/blob/master/.github/CODEOWNERS

We need only define "owners" for all crates/test code.

I could take floresta_compact_filters and floresta_mempool (@csgui could take that with me), as those are the priorities for me.

This is scoped for crates only ?

No. CODEOWNERS uses path patterns (like wildcards) to assign owners to files and folders.

CODEOWNERS can create silos in the project. For Floresta/Utreexo, where the bus factor is extremely low, this can become a barrier to knowledge sharing.

The problem is that ownership turns into gatekeeping. When specific people or teams are listed as owners of certain paths, they often become the only ones reviewing or approving changes there. And over time that discourages broader participation.

Anyway, let's try to find a solution for that.

It will only auto-request reviews, in addition to how we do it here now.

Guys, I personally feel that im happy to work in any part of the code for floresta. No one should be overcharged and im happy to be assigned where its necessary.

CODEOWNERS is bad naming so.

Lets use CODEFATHERS!
