## Summary
This change adds a link to PyPI FAQ about API tokens on the package
publishing guide page. To me it wasn't clear what are meant in this
section of the docs and it required a little bit of research. Adding
explicit link might help beginners.

## Summary
Allows `--torch-backend=auto` to detect AMD GPUs. The approach is fairly
well-documented inline, but I opted for `rocm_agent_enumerator` over
(e.g.) `rocminfo` since it seems to be the recommended approach for
scripting:
https://rocm.docs.amd.com/projects/rocminfo/en/latest/how-to/use-rocm-agent-enumerator.html.
Closes https://github.com/astral-sh/uv/issues/14086.

This PR introduces transparent Python version upgrades to uv, allowing
for a smoother experience when upgrading to new patch versions.
Previously, upgrading Python patch versions required manual updates to
each virtual environment. Now, virtual environments can transparently
upgrade to newer patch versions.
Due to significant changes in how uv installs and executes managed
Python executables, this functionality is initially available behind a
`--preview` flag. Once an installation has been made upgradeable through
`--preview`, subsequent operations (like `uv venv -p 3.10` or patch
upgrades) will work without requiring the flag again. This is
accomplished by checking for the existence of a minor version symlink
directory (or junction on Windows).
### Features
* New `uv python upgrade` command to upgrade installed Python versions
to the latest available patch release:
```
# Upgrade specific minor version
uv python upgrade 3.12 --preview
# Upgrade all installed minor versions
uv python upgrade --preview
```
* Transparent upgrades also occur when installing newer patch versions:
```
uv python install 3.10.8 --preview
# Automatically upgrades existing 3.10 environments
uv python install 3.10.18
```
* Support for transparently upgradeable Python `bin` installations via
`--preview` flag
```
uv python install 3.13 --preview
# Automatically upgrades the `bin` installation if there is a newer patch version available
uv python upgrade 3.13 --preview
```
* Virtual environments can still be tied to a patch version if desired
(ignoring patch upgrades):
```
uv venv -p 3.10.8
```
### Implementation
Transparent upgrades are implemented using:
* Minor version symlink directories (Unix) or junctions (Windows)
* On Windows, trampolines simulate paths with junctions
* Symlink directory naming follows Python build standalone format: e.g.,
`cpython-3.10-macos-aarch64-none`
* Upgrades are scoped to the minor version key (as represented in the
naming format: implementation-minor version+variant-os-arch-libc)
* If the context does not provide a patch version request and the
interpreter is from a managed CPython installation, the `Interpreter`
used by `uv python run` will use the full symlink directory executable
path when available, enabling transparently upgradeable environments
created with the `venv` module (`uv run python -m venv`)
New types:
* `PythonMinorVersionLink`: in a sense, the core type for this PR, this
is a representation of a minor version symlink directory (or junction on
Windows) that points to the highest installed managed CPython patch
version for a minor version key.
* `PythonInstallationMinorVersionKey`: provides a view into a
`PythonInstallationKey` that excludes the patch and prerelease. This is
used for grouping installations by minor version key (e.g., to find the
highest available patch installation for that minor version key) and for
minor version directory naming.
### Compatibility
* Supports virtual environments created with:
* `uv venv`
* `uv run python -m venv` (using managed Python that was installed or
upgraded with `--preview`)
* Virtual environments created within these environments
* Existing virtual environments from before these changes continue to
work but aren't transparently upgradeable without being recreated
* Supports both standard Python (`python3.10`) and freethreaded Python
(`python3.10t`)
* Support for transparently upgrades is currently only available for
managed CPython installations

## Summary
I follow the advices from the IDE spell checker and grammar checker, fix
some typos, and improve the docs.
Extends https://github.com/astral-sh/uv/pull/13841 — I'll drop that
commit later after that pull request merges but it's small.
I find the split into a "Configuration" section awkward and don't think
it's helping us. Everything moved into the "Concepts" section, except
the "Environment variables" page which definitely belongs in the
reference and the "Installer" page which is fairly niche and seems
better in the reference.

## Summary
This change adds a new integration guide, on using uv with marimo
notebooks. It is similar to but simpler than the existing Jupyter guide,
since marimo stores notebooks as Python files and also integrates
tightly with uv for package management.
The guide showcases four ways of using uv with marimo:
1. marimo as a standalone tool (`uvx`)
2. managing inline script metadata (an alternative to Jupyter kernels,
marimo has no concept of kernels)
3. in project environments
4. in non-project environments
## Test Plan
N/A as this is a docs-only change.

## Summary
When creating the `.pre-commit-config.yaml` from scratch, although
following https://pre-commit.com/, it might be easy to overlook that the
pre-commit repo examples need to be added below the `repos` list item to
get a valid `yaml` file.
Additionally, updated the version of the first two examples.
## Test Plan
I followed the `CONTRIBUTING.md` and the result looked fine.

## Summary
Now that Python 3.14 first beta is out, I think it's worth adding
support for the official upstream RC images.
Once 3.14 is released, we can remove the `-rc-` infix from the images we
pull from.
## Test Plan
Upstream images verified to be functional with uv.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Incorrect use of the indefinite article- 'an project' instead of 'a
project'
## Test Plan
<!-- How was it tested? -->
Was not tested due to it being a small change to docs wording without
change in formatting.
## Summary
Replace `--frozen` with `--locked` in Docker integration guide.
`--locked` additionally validates that `uv.lock` is "fresh"/up to date,
which will catch errors if the user accidentally updated
`pyproject.toml` but did not run `uv lock` before building the
container. This is probably a better/safer default to recommend to users
to avoid surprising/incorrect behavior.
## References
- External guides already recommend using `--locked` instead of
`--frozen`
- https://hynek.me/articles/docker-uv/
- @zanieb seemed to indicate they might agree that `--locked` would be
better to avoid surprises
- https://github.com/astral-sh/uv/issues/10793#issuecomment-2743956736
## Test Plan
Used `--locked` in `uv` Python projects using Docker and validated that
it works as expected.
