New Features

• Provider availability ledger: records each model's health status and cooldown, auto-throttling on anomalies.
• Dynamic-scheduling admin: platform / model registration, quota-source labels, and call-trend viewing (replacing command-line operations).

Bug Fixes

• Retired the command registry (no callers, plotting chain doesn't validate it), reducing redundancy.
• Fixed several availability risks from free-model decommissioning/replacement and EOL model switching.
