Currently, it's possible to break our test suite by having an env var set that influences uv, either a `UV_*` var, or something more generic such as the XDG env vars. We previously fixed them env-var-by-env-var as we discovered. By clearing the env var for subcommands entirely, we can invert this to only include the env vars we care about.
Notable limitations are that this only affects tests that use `TestContext::add_shared_env` (default, can be opted-out) and we still pass a (modified) `PATH`.

## Summary
Fixes#16285
## Test Plan
<!-- How was it tested? -->
Sometimes a credential's `Debug` formatted value appears in tracing logs
- make sure the credential doesn't appear there.
## Test plan
Added a test case + ran
```
uv pip install --default-index $PYX_API_URL/$SOME_INDEX $SOME_PACKAGE -vv
```
With an authenticated uv client and confirmed the tokens are obfuscated.

## Summary
- Move parsing `UV_CONCURRENT_INSTALLS`, `UV_CONCURRENT_BUILDS` and
`UV_CONCURRENT_DOWNLOADS` to `EnvironmentOptions`
Relates https://github.com/astral-sh/uv/issues/14720
## Test Plan
- Tests with existing tests
- Add test with invalid parsing

## Summary
Adds the version for environment variables added in
https://github.com/astral-sh/uv/pull/16040 and
https://github.com/astral-sh/uv/pull/16125. as these were in-flight
before documentation versioning was added.
Adds ability to emit a compiler error when added in is missing for
improved reporting to the developer.
e.g. example for the ones fixed in this PR
```shell
error: missing #[attr_added_in("x.y.z")] on `UV_UPLOAD_HTTP_TIMEOUT`
note: env vars for an upcoming release should be annotated with `#[attr_added_in("next release")]`
--> crates\uv-static\src\env_vars.rs:593:15
|
593 | pub const UV_UPLOAD_HTTP_TIMEOUT: &'static str = "UV_UPLOAD_HTTP_TIMEOUT";
| ^^^^^^^^^^^^^^^^^^^^^^
error: missing #[attr_added_in("x.y.z")] on `UV_WORKING_DIRECTORY`
note: env vars for an upcoming release should be annotated with `#[attr_added_in("next release")]`
--> crates\uv-static\src\env_vars.rs:1087:15
|
1087 | pub const UV_WORKING_DIRECTORY: &'static str = "UV_WORKING_DIRECTORY";
| ^^^^^^^^^^^^^^^^^^^^
error: could not compile `uv-static` (lib) due to 2 previous errors
```
Cargo is currently recompiling uv-python on every invocation because the
minified JSON output file is getting a mod time newer than the last run.
Instead, set the mod time of the output file to the same as the input
file.
## Summary
When specifying constraints or overrides in combination with
`pylock.toml` as an input to `uv pip install`,
the error messages are not currently correct.
## Test Plan
No testing, it's a straightforward error string fix.

## Summary
- Move parsing `UV_HTTP_TIMEOUT`, `UV_REQUEST_TIMEOUT` and
`HTTP_TIMEOUT` to `EnvironmentOptions`
- Add new env varialbe `UV_UPLOAD_HTTP_TIMEOUT`
Relates https://github.com/astral-sh/uv/issues/14720
## Test Plan
Tests with existing tests
I think this is ostensively breaking, though I think the impact would be
small given this will go out in 0.9.1 and should only affect people
using pre-release Python versions.
When `3.14.0` is requested (opposed to `3.14`), we treat this as a
request for a final / stable version and ignore pre-releases.
I think this is a fairly clean way to allow users to explicitly request
the stable version.
Closes https://github.com/astral-sh/uv/issues/16175
Follows #16208
## Summary
Fixes [1633](https://github.com/astral-sh/uv/issues/16133). Preserves
comments preceding "version = ..." line when uv version --bump is ran
## Test Plan
Added IT test

We're regularly get questions about this. The DPO thread is the best
ressource, but it's also a long read, so I summarized some points for
uv's decision.

First commit is refactoring, second commit is the actual change.
The h2 errors, a specific type nested in reqwest errors, all look like
they shouldn't happen in regular operations and should be retried. This
covers all `io::Error`s going through h2 (i.e., only HTTP 2
connections).
Fixes https://github.com/astral-sh/uv/issues/15916
## Summary
As new environment variables get introduced (e.g. `UV_EDITABLE`) I
thought it would useful to start tracking which release they were
introduced. I think its a common workflow to navigate to the [env var
documentation](https://docs.astral.sh/uv/reference/environment) to know
what the env var for something is but then end up in a situation where
one is using an environment variable with the wrong version of uv and
not notice immediately that its not compatible and therefore ignored.
## Test Plan
Existing tests.
The versions in `since` have all been manually reviewed to the best of
my ability for correctness.
