Release v7.16.0

Added

• Claude subscription conversations through the official Claude Code CLI, with streaming responses, native caller functions, structured output, and usage reporting. Requires Claude Code on the service PATH and Unix owner-only temporary files. See subscription transport.
• Default Claude Code model aliases for subscription providers without a model catalog: Fast uses Haiku, Balanced uses Sonnet, and Powerful/Premier use Opus. Explicit model mappings and discovered catalogs take precedence.

Fixed

• Subscription pool calls stop failover after any native function invocation attempt, including failed or in-flight attempts, so automatic retries cannot repeat uncertain tool effects.
• Protected provider credentials that have not been released for use now fail with an actionable reconfiguration error instead of reaching outbound transports as encrypted envelopes.
