v1.110.0

This release adds dynamic MCP HTTP headers, new shell safety policies, per-model custom pricing, and cache-stable dynamic prompts, along with fixes for elicitation delivery and session cost tracking.

What's New

• Adds dynamic MCP HTTP headers via a header factory, enabling context-aware HTTP header resolution instead of static headers fixed at startup
• Adds a safe-auto safety policy for shell operations, providing a middle ground between prompting for every tool call and --yolo mode; safe calls beyond shell are auto-approved under this policy, with an opt-in safer mode available via approve-safer resume
• Adds an optional cost block to model configuration, allowing explicit per-model token pricing for custom, locally-hosted, or uncatalogued models
• Adds opt-in cache-stable dynamic prompts (cache_stable_prompts user setting), persisting frozen instruction snapshots and appending chronological updates when trusted context changes

Bug Fixes

• Fixes elicitation requests from concurrent background jobs being silently dropped and blocking the requesting handler indefinitely
• Fixes session cost dropping after compaction (e.g., from $49 to $12) by keeping cost monotonic across compaction and preserving cost accounting across reload
