/**
|
|
* One-time migration: Member.contributionTier (String: "0"|"5"|"15"|"30"|"50") →
|
|
* Member.contributionAmount (Number). Idempotent: only acts on docs that still
|
|
* have contributionTier; safe to re-run.
|
|
*
|
|
* Usage:
|
|
* node scripts/migrate-contribution-amount.cjs # dry-run (default)
|
|
* node scripts/migrate-contribution-amount.cjs --apply # writes changes
