Enhances bit ci merge command with automatic version bump detection from commit messages, eliminating the need to manually specify version flags in many cases.

Auto-detection priority:

1. Explicit keywords: BIT-BUMP-MAJOR, BIT-BUMP-MINOR in commit message
2. Conventional commits: feat\!:/BREAKING CHANGE → major, feat: → minor, fix: → patch
3. Default: patch version bump

Key features:

• Only triggers when no explicit version flags (--patch, --minor, --major) are provided
• Configurable via useConventionalCommitsForVersionBump and useExplicitBumpKeywords in workspace.jsonc
• Includes CircleCI wrapper script for environment variable support (VERSION_BUMP_TYPE)
• Comprehensive documentation with examples

Example usage:

git commit -m "feat: add new API endpoint"
bit ci merge --build  # → auto-detects minor bump

git commit -m "feat: add feature BIT-BUMP-MINOR"  
bit ci merge --build  # → auto-detects minor bump
