Add in-REPL session restoration and read-only config inspection so the CLI can recover saved conversations and expose Claude settings without leaving interactive mode. /resume now reloads a session file into the live runtime, and /config shows discovered settings files plus the merged effective JSON.
The new commands stay on the shared slash-command surface and rebuild runtime state using the current model, system prompt, and permission mode so existing REPL behavior remains stable.
Constraint: /resume must update the live REPL session rather than only supporting top-level --resume
Constraint: /config should inspect existing settings without mutating user files
Rejected: Add editable /config writes in this slice | read-only inspection is safer and sufficient for immediate parity work
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep resume/config behavior on the shared slash command surface so non-REPL entrypoints can reuse it later
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: manual interactive restore against real saved session files outside automated fixtures
