Normalize Anthropic-owned Opus 4.7 context reporting to 1M while keeping inferred and bare discovery paths conservative.
- normalize Anthropic and claude-cli Opus 4.7 runtime/status context metadata to 1M
- keep inferred-provider and bare discovery ids on discovered conservative limits
- add regression coverage for provider, lookup, status, and discovery-cache paths
- keep the Telegram abort-signal wrapper typing narrow so changed-scope validation stays green
