[Feature Request] Promo account sharing - Share quota with friends via referral link

Feature: Promo Account Sharing

Allow users to generate sharing links so friends can use Z.ai products (GLM, chat.z.ai) charged against the original user quota.

Concept:

User A generates link -> Friend B clicks -> Friend uses product -> Charged to User A quota

"Your friend wants to try GLM out, you give him a link and as he is using the product - your quota gets drained." — DCCCXIX

Link Types:

• Quota-limited ($5/$10/$20)
• Time-limited (24h/7d/30d)
• One-time or unlimited (revocable)

Business Value:

• Viral growth, zero acquisition cost
• Product-led growth, no friction
• High trust via friend recommendations
• Trial users likely convert to paid

Security Limits:

• Free: 1 link, $10/month, 5 recipients
• Paid: 5 links, $50/month, 25 recipients
• Pro: Unlimited + revenue share

Phases:

1. MVP: Basic share links + dashboard
2. Analytics + time-limited links
3. Revenue share + API access

The issue names no repository files, tests, or implementation entry points. Start by turning the proposed link types, quota limits, recipient limits, revocation, dashboard, and phased analytics into agreed requirements, then identify the account, quota, and product-access components they affect. Done requires a maintainer-approved scope and acceptance criteria before implementation begins.
