## Summary
Adds a new workflow that generates an ecosystem report of all
diagnostics and publishes it to Cloudflare pages.
## Test Plan
Not yet tested.
## Summary
Pulls in two fixes and a performance optimization:
- Fix a bug with the Markdown table formatting.
- Combine the two `analyze` commands into a single `diff` command. This
means we only need to set up the projects once, which is faster and also
avoids a race condition where projects could change between the two
`analyze` runs.
## Summary
Changes the ecosystem-analyzer workflow to deploy the diff to Cloudflare
pages and post a link in the PR. Also adds a summary statistics to that
PR comment.
## Test Plan
The comment below:
https://github.com/astral-sh/ruff/pull/19234#issuecomment-3053205937. I
previously had some dummy changes on this PR to see a non-zero diff. And
I didn't reapply the label after I reverted that change, such that it's
still visible for reviewers.

[`v6.3.1`](https://redirect.github.com/astral-sh/setup-uv/releases/tag/v6.3.1):
🌈 Do not warn when version not in manifest-file
[Compare
Source](https://redirect.github.com/astral-sh/setup-uv/compare/v6.3.0...v6.3.1)
##### Changes
This is a hotfix to change the warning messages that a version could not
be found in the local manifest-file to info level.
A `setup-uv` release contains a version-manifest.json file with infos in
all available `uv` releases. When a new `uv` version is released this is
not contained in this file until the file gets updated and a new
`setup-uv` release is made.
We will overhaul this process in the future but for now the spamming of
warnings is removed.

## Summary
Print the [new salsa memory usage
dumps](https://github.com/astral-sh/ruff/pull/18928) in mypy primer CI
runs to help us catch memory regressions. The numbers are rounded to the
nearest power of 1.1 (about a 5% threshold between buckets) to avoid overly sensitive diffs.
## Summary
Adds a new ecosystem-analyzer workflow with a similar purpose to the
mypy-primer workflow. It creates a richer ecosystem diff report using
[ecosystem-analyzer](https://github.com/astral-sh/ecosystem-analyzer/)
([example
report](https://shark.fish/diff-attr-subscript-narrowing.html)). This is
still experimental and also quite a bit slower than mypy_primer, so I
chose to make this opt-in for now via a `ecosystem-analyzer` label. This
would give us a way to play with this while still evaluating if we
should further invest in this or not.
Advantages over the mypy_primer diff output:
- Interactive filtering of diagnostics
- Statistics overview which breaks down added/removed/changed
diagnostics across lint rules
- Has the concept of "changed" diagnostics, which makes it easier to
review changes where diagnostic messages have changed (along with other
changes).
- Compute diff based on old and new project-lists (`good.txt`). This
allows us to diff changes to the project list itself. This has caused
confusion in the past where we tried to add new projects to `good.txt`,
but then ran the `main`-branch version of ty on that new list (where the
bug was not yet fixed)
Disadvantages:
- The report currently needs to be downloaded from the workflow run, as
I don't know if we have a way of deploying HTML files like this
temporarily to some hosted infrastructure.
## Summary
I think `division-by-zero` is a low-value diagnostic in general; most
real division-by-zero errors (especially those that are less obvious to
the human eye) will occur on values typed as `int`, in which case we
don't issue the diagnostic anyway. Mypy and pyright do not emit this
diagnostic.
Currently the diagnostic is prone to false positives because a) we do
not silence it in unreachable code, and b) we do not implement narrowing
of literals from inequality checks. We will probably fix (a) regardless,
but (b) is low priority apart from division-by-zero.
I think we have many more important things to do and should not allow
false positives on a low-value diagnostic to be a distraction. Not
opposed to re-enabling this diagnostic in future when we can prioritize
reducing its false positives.
