style: cargo fmt — fix CI formatting failures

Pre-existing formatting issues in anthropic.rs surfaced by CI cargo fmt check.
No functional changes.

 19. **Subcommand help falls through into runtime/API path** — **done**: `claw doctor --help`, `claw status --help`, `claw sandbox --help`, and nested `mcp`/`skills` help are now intercepted locally without runtime/provider startup, with regression tests covering the direct CLI paths.
 20. **Session state classification gap (working vs blocked vs finished vs truly stale)** — **done**: agent manifests now derive machine states such as `working`, `blocked_background_job`, `blocked_merge_conflict`, `degraded_mcp`, `interrupted_transport`, `finished_pending_report`, and `finished_cleanable`, and terminal-state persistence records commit provenance plus derived state so downstream monitoring can distinguish quiet progress from truly idle sessions.
 21. **Resumed `/status` JSON parity gap** — dogfooding shows fresh `claw status --output-format json` now emits structured JSON, but resumed slash-command status still leaks through a text-shaped path in at least one dispatch path. Local CI-equivalent repro fails `rust/crates/rusty-claude-cli/tests/resume_slash_commands.rs::resumed_status_command_emits_structured_json_when_requested` with `expected value at line 1 column 1`, so resumed automation can receive text where JSON was explicitly requested. **Action:** unify fresh vs resumed `/status` rendering through one output-format contract and add regression coverage so resumed JSON output is guaranteed valid.
-22. **Opaque failure surface for session/runtime crashes** — repeated dogfood-facing failures can currently collapse to generic wrappers like `Something went wrong while processing your request. Please try again, or use /new to start a fresh session.` without exposing whether the fault was provider auth, session corruption, slash-command dispatch, render failure, or transport/runtime panic. This blocks fast self-recovery and turns actionable clawability bugs into blind retries. **Action:** preserve a short user-safe failure class (`provider_auth`, `session_load`, `command_dispatch`, `render`, `runtime_panic`, etc.), attach a local trace/session id, and ensure operators can jump from the chat-visible error to the exact failure log quickly.
+22. **Opaque failure surface for session/runtime crashes** — **done**: `safe_failure_class()` in `error.rs` classifies all API errors into 8 user-safe classes (`provider_auth`, `provider_internal`, `provider_retry_exhausted`, `provider_rate_limit`, `provider_transport`, `provider_error`, `context_window`, `runtime_io`). `format_user_visible_api_error` in `main.rs` attaches session ID + request trace ID to every user-visible error. Coverage in `opaque_provider_wrapper_surfaces_failure_class_session_and_trace` and 3 related tests.
 23. **`doctor --output-format json` check-level structure gap** — **done**: `claw doctor --output-format json` now keeps the human-readable `message`/`report` while also emitting structured per-check diagnostics (`name`, `status`, `summary`, `details`, plus typed fields like workspace paths and sandbox fallback data), with regression coverage in `output_format_contract.rs`.
 24. **Plugin lifecycle init/shutdown test flakes under workspace-parallel execution** — dogfooding surfaced that `build_runtime_runs_plugin_lifecycle_init_and_shutdown` can fail under `cargo test --workspace` while passing in isolation because sibling tests race on tempdir-backed shell init script paths. This is test brittleness rather than a code-path regression, but it still destabilizes CI confidence and wastes diagnosis cycles. **Action:** isolate temp resources per test robustly (unique dirs + no shared cwd assumptions), audit cleanup timing, and add a regression guard so the plugin lifecycle test remains stable under parallel workspace execution.
 26. **Resumed local-command JSON parity gap** — **done**: direct `claw --output-format json` already had structured renderers for `sandbox`, `mcp`, `skills`, `version`, and `init`, but resumed `claw --output-format json --resume <session> /…` paths still fell back to prose because resumed slash dispatch only emitted JSON for `/status`. Resumed `/sandbox`, `/mcp`, `/skills`, `/version`, and `/init` now reuse the same JSON envelopes as their direct CLI counterparts, with regression coverage in `rust/crates/rusty-claude-cli/tests/resume_slash_commands.rs` and `rust/crates/rusty-claude-cli/tests/output_format_contract.rs`.
