manifest v5.58.0

✨ Minor Changes

• 992ae47: Add saved cost metric to the Overview dashboard showing how much money routing saves compared to using a single model

🐛 Patch Changes

• 7394235: Mark Manifest's canned setup-prompt and limit responses as Failed in the Messages list. Requests that hit no_provider, no_provider_key, limit_exceeded, or friendly_error (the [🦚 Manifest] … stubs) now show a red Failed badge with a tooltip explaining why, instead of an ambiguous green Success.
• 4bd4039: Fix two routing regressions caused by agent-wrapped user messages. Strip leading metadata envelopes (e.g. Sender (untrusted metadata): blocks emitted by OpenClaw, NanoBot, Hermes) before scoring so simple greetings like "say hello" no longer route to standard/complex (#1766). Tighten coding specificity signals so generic agent tools (read, write, edit, bash, etc.) and tiny envelope code fences no longer hijack every prompt to the coding tier (#1767).
