evandance 99e314fe0b feat(errs): typed envelope contract for auth-domain errors (#1135)
Every failure on the authentication, authorization, and configuration
path now surfaces as a typed structured error instead of an ad-hoc
envelope. Users and scripts that consume CLI output get:

  - a fixed nine-category taxonomy on the wire, each mapped to a
    stable shell exit code (authentication/authorization/config = 3,
    network = 4, internal = 5, policy = 6, confirmation = 10)
  - identity-aware detail fields (missing_scopes, requested_scopes,
    granted_scopes, console_url, log_id, retryable, hint) carried
    uniformly on the envelope
  - a single canonical policy envelope at exit 6; the legacy
    auth_error carve-out is retired
  - per-subtype canonical message + hint that preserves Lark's
    diagnostic phrasing and routes recovery to the right actor:
    app developer (app_scope_not_applied), user (missing_scope,
    token_scope_insufficient, user_unauthorized), or tenant admin
    (app_unavailable, app_disabled)
  - wrong app credentials classify as config/invalid_client whether
    surfaced by the Open API endpoint (99991543) or the tenant
    access-token mint endpoint (10003 / 10014), instead of
    collapsing to a transport error or api/unknown
  - local shortcut scope preflight emits the same
    authorization/missing_scope envelope (identity + deterministic
    missing-scope set) used by the post-call permission path, so AI
    consumers read the same structured shape from precheck and from
    server-returned permission denial
  - streaming download/upload failures keep the same network subtype
    split (timeout / TLS / DNS / transport) as the non-stream path
    instead of collapsing every cause to a generic transport failure
  - console_url is carried only on the bot-perspective
    app_scope_not_applied envelope (where the recovery action is
    "developer applies the scope at the developer console"); the
    user-perspective missing_scope envelope drops the field, since
    the only actionable user recovery is `lark-cli auth login --scope`
    and pointing an end user at a console they cannot modify is
    misleading
  - bind workflows (Hermes / OpenClaw / lark-channel) flatten dynamic
    Type tags to wire 'config' with the original module name kept
    as a metric label

All 10 typed errors are cause-bearing, nil-safe on .Error() and
.Unwrap(), and defensively clone slice setter inputs. Four lint
rules (CheckNilSafeError / CheckBuilderImmutable / CheckUnwrapSymmetry
/ CheckBuildAPIErrorArms) lock these invariants on migrated paths.
