fix: remove push=false blocking VCS releases

[doughayden]

Summary

Fixes semantic-release not creating tags/releases by removing the push = false configuration that was blocking VCS operations.

Problem

Workflow logs showed:

INFO [version.version] No vcs release will be created because pushing changes is disabled

The push = false setting was preventing all VCS operations, including tag and release creation, not just commit pushes.

Solution

Configuration changes:

1. Remove push = false from pyproject.toml
2. Remove push: "false" from workflow parameters
3. Keep commit = false to prevent version bump commits

Expected behavior:

• ✅ Tags created - Semantic version tags will be pushed to GitHub
• ✅ Releases created - GitHub releases with auto-generated notes
• ❌ No commits - commit = false prevents version bump commits to main
• ❌ No branch pushes - Protected branch rules still enforced

Key Insight

Semantic-release interprets push = false as "disable all remote operations" rather than "don't push commits". Since we have commit = false, there are no commits to push anyway - removing push = false only enables tag/release creation.

Testing Plan

• Merge PR to main
• Verify workflow creates actual tags: git tag --list
• Verify GitHub releases created: gh release list
• Confirm no commits pushed to main branch
• Validate release contains distribution artifacts

Resolves

• Fixes fix: semantic-release not creating tags/releases despite success #26 (semantic-release not creating tags/releases)
• Completes tag-based release workflow implementation
