feat(clients): CLI-04 typed single-item command parity (+CLI-30 unregister) — 4/5 clients
Every parity-critical single-item MXAccess command now has a typed session helper instead of only a raw-Invoke escape hatch. Added per client: - Phase 1: AdviseSupervisory, WriteSecured, WriteSecured2, AuthenticateUser, ArchestrAUserToId - Phase 2: AddBufferedItem, SetBufferedUpdateInterval, Suspend, Activate - CLI-30: Unregister (Rust + .NET; Go/Python already had it) Each wraps the existing raw-command machinery (no new wire surface) and runs the same MXAccess-level reply validation (hresult < 0 + MxStatusProxy). MXAccess parity preserved: WriteSecured before AuthenticateUser+AdviseSupervisory surfaces the native failure unchanged (not pre-validated/reordered). Credentials (AuthenticateUser password, WriteSecured payloads) route through each client's secret-redaction seam and never reach logs/exceptions/ToString/Debug/Display; each suite asserts a distinctive credential is absent from surfaced errors. New CLI subcommands source credentials via flag/env, never echoed. - .NET: 21 helpers (validated + Raw), CLI subcommands, multi-secret CLI redactor. Build clean (0 warn), 102 passed. - Go: 9 helpers + *Raw variants, redactSecrets seam, promoted CLI advise-supervisory to typed. gofmt/vet/build/test clean. - Rust: 10 helpers incl. unregister; verified ensure_mxaccess_success runs on secured paths; error.rs credential scrub. fmt/check/test/clippy clean. - Python: 9 async helpers, redact_secret seam + _invoke_redacted, CLI commands. 145 passed. - Shared doc: ClientLibrariesDesign "Typed Command Parity" section. Java client typed parity is batched to windev (no local JRE); CLI-04 + CLI-30 stay open until it lands. Claude-Session: https://claude.ai/code/session_01DMXXvNuPekkkrTEyPNxEkW
