# Claim or release a Gitea issue by toggling the `status:in-progress` label, so
# parallel agents/LLMs don't pick up the same issue.
#
# Usage:
#   ./mark_issue.sh <issue_number>          # claim   (adds status:in-progress)
#   ./mark_issue.sh <issue_number> start    # claim
#   ./mark_issue.sh <issue_number> done     # release (removes the label)
#
# Auth: macOS keychain via `git credential fill` (same as the other scripts).
