Takes one or more CSV files as positional arguments, extracts repo slugs from the first column, deduplicates across all inputs, and archives each via gh repo archive --yes. Runs in dry-run mode by default — set APPLY=1 to actually archive, since GitHub's API has no bulk un-archive operation. Each archive attempt is logged to archive-log.csv with…

# archive-repos.sh
#
# Archive GitHub repos listed in one or more CSV files. Reads the first
# column (repo slug) of each CSV, deduplicates across files, and calls
# `gh repo archive --yes` on each.
#
# Defaults to DRY RUN — prints what would happen but doesn't touch anything.
# Set APPLY=1 to actually archive. Note: GitHub's API does NOT support
# un-archiving in bulk, so review the dry-run output carefully first.
#
# Usage:    bash archive-repos.sh <csv> [<csv> ...]           # dry run
#           APPLY=1 bash archive-repos.sh <csv> [<csv> ...]   # real archive
# Defaults: LOG=archive-log.csv  APPLY=0
# Outputs:  archive-log.csv  (repo, status, detail)   — only when APPLY=1
