Pull request overview

This PR introduces a new GitHub Actions workflow for creating "shadow releases" of the XELP branch. The workflow automatically calculates a modified version number (adding 100 to the major version), builds the project, and publishes it to a separate xelp/dist branch with an appropriate version tag.

• Creates versioned shadow releases from the xelp/main branch
• Automates version calculation with a unique naming scheme (major+100, with date and commit hash metadata)
• Builds and commits the distribution files to a dedicated branch with version tagging

.github/workflows/xelp_shadow_release.yml:1

• Array splitting logic can fail silently. When IFS='.' read splits the version string on line 38, if the version has fewer than 3 parts, the PARTS array will have fewer elements. Accessing ${PARTS[1]} or ${PARTS[2]} on lines 44-45 won't fail in bash but will result in empty strings, bypassing the check on line 39. This check should be performed immediately after the split, or use safer array access patterns. Move the validation block (lines 39-42) immediately after line 38, before any variable assignments.
