5 features, 6 bug fixes, 2 docs, and 4 chores.

Details in thread ↓

[Codex Changelog @CodexLog]

Chores:
• Added a faster Cargo profiling build profile and disabled empty doctest targets to speed up Rust development loops.
• Hardened dependency and CI hygiene with fully qualified GitHub Action pins, a Dependabot cooldown, and a cargo-shear upgrade.
• Simplified internal surfaces by removing unused device-key APIs, extra skills roots, the remote thread-store implementation, and string-keyed MCP tool maps.
• Added configurable OpenTelemetry trace metadata and richer review/feedback analytics for better debugging and triage.

Details in thread ↓

[Codex Changelog @CodexLog]

Docs:
