cad-config

Manage `.planning/config.json` (template in `cadence-core/templates/config.json`). One skill for the whole config; its substantive part is review-provider model assignment, which needs live detection (call the provider models endpoint, classify, assign per tier).

Routing:

• --review [redetect]: run the cross-model review-provider setup - detect each provider's accessible models and assign them to the flagship/balanced/ cheap tiers.
• <key>=<value> ...: set config keys directly (validated against the config schema).
• default (no args): walk every knob as a selectable list (batched pages), each preselected to its current value.

<execution_context> @${CLAUDE_PLUGIN_ROOT}/cadence-core/workflows/config.md </execution_context>

Parse `$ARGUMENTS`, then execute the matching branch of the config workflow end-to-end. Never write an invalid config; never block the spine on a network call (detection degrades to claude-subagent).
