First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
## Summary
This ensures that (like Cargo) we don't suffer from
https://github.com/advisories/GHSA-r5w3-xm58-jv6j, by way of checking
known hosts when fetching via `libgit2`.
The implementation is taken from Cargo itself, modified to remove all
configuration, since we don't yet support configuration for known hosts,
etc.
Closes#285.
