Close the Claude Code tools parity gap

Browse Source 
Implement the remaining long-tail tool surfaces needed for Claude Code parity in the Rust tools crate: SendUserMessage/Brief, Config, StructuredOutput, and REPL, plus tests that lock down their current schemas and basic behavior. A small runtime clippy cleanup in file_ops was required so the requested verification lane could pass without suppressing workspace warnings.

Constraint: Match Claude Code tool names and input schemas closely enough for parity-oriented callers
Constraint: No new dependencies for schema validation or REPL orchestration
Rejected: Split runtime clippy fixes into a separate commit | would block the required cargo clippy verification step for this delivery
Rejected: Implement a stateful persistent REPL session manager | unnecessary for current parity scope and would widen risk substantially
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: If upstream Claude Code exposes a concrete REPL tool schema later, reconcile this implementation against that source before expanding behavior
Tested: cargo fmt --all; cargo clippy -p tools --all-targets --all-features -- -D warnings; cargo test -p tools
Not-tested: End-to-end integration with non-Rust consumers; schema-level validation against upstream generated tool payloads
