fix: pin toolchain versions to specific constituent package versions
Toolchain meta-packages now use data.json to explicitly pin constituent package versions instead of following .default, making toolchain versions immutable. Introduces v2 with post-bump versions and keeps v1 at pre-bump. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
