### BREAKING CHANGES

* **info:** `toolchain_info#variable` now defaults to the basename of the target executable.

Previously the variable defaulted to the `name` attribute:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    # variable = "DEF",
)
```

Now the rule defaults the basename of the target executable:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    # variable = "ABC",
)
```

In most situations, this is the prefered default.

In cases where the name is the variable name wanted, the `variable` now needs to be added:

```py
go_binary(
    name = "abc,
)

toolchain_info(
    name = "def",
    target = ":abc",
    variable = "ABC",
)
```
* **info:** `toolchain_info` removes `ToochainInfo#env`.

Allowing access to the original `env` attribute of the `toolchain_info` target can result in unexpected errors. `env` is usual subject to Make variable and expand location expansion. The expansion is done in the scope of the original rule. Re-using the environment results in errors with miscalculated paths, etc.

If it is required to capture the environment variables for a binary, it is much better to use a rule that bakes the environment variables into the execution of the binary. This can be done with launcher scripts that write out the environment variables for later use.
* **info:** `variables` is no longer available on the `ToolchainInfo` generated by `toolchain_info`.

The `TemplateVariableInfo` is created in the scope of the `toolchain_info` rule. Using the provider in downstream rules that access the `ToolchainInfo` will no longer be relevant.

A `ToolchainInfo#variable` attribute is provided to reconstruct a `TemplateVariableInfo` in the scope of a downstream rule.
* **resolved:** The `resolved` repository rule has removed the `basename` attribute in favour or symlinking the binary directly.

This change prevents unwanted symlink basename changes which can prevent multi-tool binaries from functioning correctly.

To set the basename of a symlink use the `toolchain_symlink_target` rule.
* **toolchain_local_select:** `toolchain_local_select#map` is now flipped taking the labels as they keys rather than as the values.

Previous releases had the following setup:

```py
download_file(
    name = "abc-arm64-linux-gnu",
    output = "abc",
)

download_file(
    name = "abc-arm64-linux-musl",
    output = "abc",
)

toolchain_local_select(
    name = "abc",
    map = {
        "arm64-linux-gnu": "@abc-arm64-linux-gnu",
        "arm64-linux-musl": "@abc-arm64-linux-musl",
    },
)
```

This prevented eagarly overfetching all the repositories that would be
selected. As of Bazel 7.4.0+[1], it no longer overfetches so the `map`
attribute has been switched to a `label_keyed_string_dict`:

```py
toolchain_local_select(
    name = "abc",
    map = {
        "@abc-arm64-linux-gnu": "arm64-linux-gnu",
        "@abc-arm64-linux-musl": "arm64-linux-musl",
    },
)
```

The repository rule will _only_ fetch the repostory label that has been selected due
to the triplet value matching.

Whilst this is a breaking change, it will introduce a regression on Bazel 7.3 and below
which will overfetch the repositories. It is *highly* recommended to use Bazel 7.4 and above.

* `ToolchainInfo#inherited` removed

It is not possible to use these in an action as the host
environment variables cannot be read host environment variables.
* The `toolchain_symlink_target` no longer exports
`ToolchainInfo`/`TemplateVariableInfo`.

The `toolchain_info` can provide those providers. The `toolchain_symlink_target`
is purely for creating a symlink to a previous target. This still enables
changing the basename for multi-call binaries.

To gain the old functionality, if `basename` attribute is not being used,
`toolchain_symlink_target` can be switched directly for `toolchain_info`. If
`basename` is being used, an extra `toolchain_info` rule will need to be created
to wrap the `toolchain_symlink_target` rule.
* **symlink/target:** the `files_to_run` property has been removed from the `ToolchainInfo` provider. Use `info.default.files_to_run` instead.

A new `info.run` has been added that is `info.default.files_to_run` or `info.default.executable`.
This is a convenience property that can be passed to `ctx.actions.run#execute`.
* **symlink/target:** `toolchain_symlink_path` no longer provides `ToolchainInfo`/`TemplateVariableInfo`.

It is required to use `toolchain_symlink_target` to the `toolchain_symlink_path`.

This is due to `toolchain_symlink_target` needing to export the `DefaultInfo.file_to_run` from the
symlinked target. That is not possible with a filesystem path.

This should not affect most users as `toolchain_symlink_path` is mainly used in `toolchain_local_which`.

If `toolchain_symlink_path` is being used, then to gain the previous functionality, create a
`toolchain_symlink_target` to the `toolchain_symlink_path` label.
