Ship the new rattler-lock-v7 canonical name alongside rattler-lock-v6 following the documented bump policy. The unversioned `pixi` alias stays on v6 during this overlap release; `pixi-lock-v7` is available as a version-pinned alias. Key v7 changes modeled: - Top-level `platforms` list (replaces implicit per-environment platforms) - `conda_source` package type for source builds - Per-environment `options` (channel-priority, strategy) - Per-package `index` for PyPI custom indexes - Split PyPI distribution/source packages The v6 export tests are updated to pass `--format=rattler-lock-v6` explicitly, since both versions now register `pixi.lock` as a default filename and conda raises PluginError on the ambiguity.
Aligns the v6 test data directory naming with pixi-v7-metadata for consistency across format versions.

Description
Add
rattler-lock-v7alongsiderattler-lock-v6for the overlap release. Keep the unversionedpixialias on v6 and emit aPendingDeprecationWarningexplaining the future alias change. Explicitrattler-lock-v6,pixi-lock-v6andpixi-lock-v7selections remain quiet.Represent v7 platform declarations, environment options, package references and PyPI metadata. Validate environment and platform selection, reject malformed or missing package references, reject unsupported
conda_sourceinstalls, and preserve PyPI references as external package metadata.Preserve explicit conda package
build_numbervalues, including zero, in the v7 model and exporter. Build numbers remain independent of build strings, and files that omit the optional field continue to use cached package metadata. This applies the same correction as #175 to v7's separate implementation. Use conda's current YAML API for the new exporter and comparison helper.Document the overlap aliases and maintainer warning policy. Filename-only export to
pixi.lockremains subject to conda/conda#15963 while both format versions register that filename.Closes #178. Related to #133 and #176.
