## Summary
Closes #2410 
<!-- What's the purpose of the change? What does it do, and why? -->
This changes the name of files in `wheels` bucket to use a hash instead
of the wheel name as to not exceed maximum file length limit on various
systems.

This only addresses the primary concern of #2410. It still does _not_
address:
- Path limit of 260 on windows:
https://github.com/astral-sh/uv/issues/2410#issuecomment-2062020882
To solve this we need to opt-in to longer path limits on windows
([ref](https://github.com/astral-sh/uv/issues/2410#issuecomment-2150532658)),
but I think that is a separate issue and should be a separate MR.
- Exceeding filename limit while building a wheel from source
distribution
As per my understanding, this is out of uv's control. Name of the output
wheel will be decided by build-backend used by the project. For wheels
built from source distribution, pip also uses the wheel names in cache.
So I have not touched `sdists` cache.


I have added a `filename: WheelFileName` field in `Archive`, so we can
use it while indexing instead of relying on the filename on disk.
Another way to do this was to read `.dist-info/WHEEL` and
`.dist-info/METADATA` and build `WheelFileName` but that seems less
robust and will be slower.
## Test Plan

<!-- How was it tested? -->
Tested by installing `yt-dlp`, `httpie` and `sqlalchemy` and verifying
that cache files in `wheels` bucket use hash.
