# Bump Beta Version Script
# Automates version bumping for Beta releases.
# Logic:
# - If current is Alpha (x.y.z-alpha), bumps to next MINOR as beta (e.g., 0.3.0 -> 0.4.0-beta.1)
# - If current is Beta (x.y.z-beta.X), bumps to x.y.z-beta.(X+1)
# - Updates .version, backend/internal/version/version.go, package.json (root/frontend/backend), VERSION.md

# VERSION.md (Optional: just appending a log or ensuring it's mentioned?
# For now, let's just leave it or maybe update a "Current Version" line if it existed.
# The user plan said "Update VERSION.md to reflect the current version".
# Let's assume we just want to ensure the file exists or maybe add a header.
# Actually, let's just print a reminder for now as VERSION.md is usually a guide.)
# But I can replace a specific line if I knew the format.
# Looking at previous read_file of VERSION.md, it doesn't seem to have a "Current Version: X" line easily replaceable.
# I will skip modifying VERSION.md content automatically to avoid messing up the guide text,
# unless I see a specific placeholder.
