Convert the Partners table indentation from spaces to tabs and add self-closing XML-style trailing slashes to void element tags in the README.

Normalizes whitespace formatting for the CrabNebula sponsor link block without altering content or structure.

The Cargo.lock file is unnecessary in a library/vendored dependency fork and can cause merge conflicts during upstream syncs. Remove it to align with the convention of treating this as a library dependency rather than an application crate.

Reduces diff noise in future upstream merges.
