v0.97.0

Minor Changes

• eea5c6b: Grok CLI: custom sub-agents interop + real skills root. Export converts subAgents entries from ~/.grok/user-settings.json into portable agents (instruction only; the per-agent model is dropped with a warning; reserved built-in names, duplicates, and instruction-less entries are warned and not migrated). Import merges portable agents back into subAgents with grok's default model, preserving all other user-settings keys and existing entries (same-name overwrites, nested-name flattening, and reserved-name skips are warned). Agent Skills now read/write grok's real root ~/.agents/skills (project .agents/skills); the legacy ~/.grok/skills root — which grok never loads — is still read on export with warnings.
