Clerk sync enforces seat caps

- Platforms are moving to seat‑based entitlements and anti‑abuse billing buckets, tying identity syncs (Clerk) to plan limits and usage controls. - Public examples show Starter plans constrained to 5 seats and Pro to 20 seats, with commit messages and tool calls reallocated to different billing buckets to prevent abuse. - Engineers warn shared budgets can cause 429s and recommend IAM‑style keys and per‑agent budgets to keep tool calls predictable.
