v1.8.0

Highlights

• Added Claude Fable 5 and limited-access Claude Mythos 5 support across OpenCode, Pi, shared model metadata, and the cache-usage analyzer.
• Added API-key fallback routes for Anthropic-compatible providers such as Kie, with API-key spending allowed only after fresh, token-bound confirmation that main OAuth quota is exhausted.
• Split editable sidecar config from runtime auth state so background refresh, quota, and routing writes cannot overwrite user-managed settings.

Fixes and improvements

• Normalized Fable/Mythos OpenCode requests by removing top-level adaptive thinking and preserving output_config.effort, matching Anthropic migration guidance.
• Show both 5-hour and 7-day quota windows in the collapsed OpenCode sidebar summary.
• Display Anthropic OAuth models as zero-cost in OpenCode while preserving token accounting and API-key model pricing.
• Bounded relay, cachekeep, and identity in-memory caches; propagated relay abort signals; improved Pi stream cancellation; and documented intentional relay tradeoffs in AUDITOR.md.
• Added opt-in request, relay, and stream performance instrumentation under OPENCODE_ANTHROPIC_AUTH_PERF=1.
