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.

Use: "keychain-downgrade",
Short: "Downgrade keychain storage to a local file (macOS only)",
Long: `Materialize the master key from the macOS system Keychain into a local file
under ~/Library/Application Support/lark-cli/master.key.file, then pin all
subsequent reads to that file.
Intended workflow: run this once from an interactive Terminal session on
macOS (where the system Keychain is reachable). After it finishes,
sandboxed / automation / CI runs of lark-cli on the same machine will read
the master key from the local file and no longer need the OS Keychain.
This is the supported fix for environments like the Codex sandbox where the
system Keychain is blocked. Running keychain-downgrade from inside such a
sandbox will itself fail with "keychain access blocked" — that is expected;
run it from an interactive macOS session instead.
The OS Keychain entry is preserved as a cold backup; nothing is deleted there.
The command is idempotent: re-running it on an already-downgraded install
reports "already downgraded" and exits 0.`,
