Add a `--from-lockfile` flag to `pixi workspace export conda-environment` that renders a frozen environment.yaml using the package versions resolved in the lock file instead of the manifest specs. Conda packages are pinned as `name ==version build`, registry PyPI packages as `name==version`, and git/file/path PyPI sources keep their direct reference URLs. Closes prefix-dev#5825 https://claude.ai/code/session_011qEmEGrK3p1pmeVAwydSc7
- Replace `pixi install` with `pixi lock` in error help text since the user just wants the lock file refreshed, not the env materialised. - Regenerate the autogenerated CLI reference page to surface the new --from-lockfile flag. - Mention the new flag in the conda switching guide. https://claude.ai/code/session_011qEmEGrK3p1pmeVAwydSc7

…k 0.29 prefix-dev#5989 added the new `pixi workspace export --from-lockfile` path against an older rattler_lock API. While that PR was open, rattler_lock split `LockedPackageRef` into a single `LockedPackage` enum, turned `PypiPackageData` into a `Distribution`/`Source` enum with method accessors (`name()`, `location()`, `version()`), removed the `editable` field, dropped `package_record` from `CondaSourceData`, and changed `Environment::packages` to take `rattler_lock::Platform<''_>` instead of `rattler_conda_types::Platform`. The PR was merged without rebasing onto those changes, so `cargo check` failed on `main` with seven errors in `crates/pixi_cli/src/workspace/export/conda_environment.rs`. This rebases the new code onto the current API: - swap `LockedPackageRef`/`LockedPackageRef::Pypi(p, _)` for `LockedPackage`/`LockedPackage::Pypi(p)` - read pypi fields through the new methods (`pypi.name()`, `pypi.location().inner()`, `pypi.version()`) - look the package up in the manifest pypi-deps for this environment + platform to decide editability instead of inferring it from the lockfile shape (transitive source pypi deps must not get rendered with `-e`) - resolve `rattler_conda_types::Platform` to `rattler_lock::Platform<''_>` via `lockfile_env.platforms().find(|p| p.subdir() == *platform)` before calling `Environment::packages` - replace `source.package_record.name.as_source()` with `source.name().as_source()` for conda source packages
