Merge branch 'main' into feat/shortcut-protocol

Two parity edge cases from a follow-up audit:

- []<named string> element types (type ID string; field []ID) passed parse
  validation but panicked at bind via reflect.Convert([]string -> []ID). Build
  the slice element-by-element with SetString (stringsToSlice) so plain
  []string, named slice types and named element types all bind correctly.
- nil Execute: mountTyped now skips mounting (matching legacy
  Shortcut.MountWithContext) instead of mounting a command that errors only at
  invocation, keeping the command tree identical after migration.

Adds binder_namedslice_nilexec_test.go (4 cases).

 ### Structured errors in commands
 
-Command-facing failures must be typed `errs.*` errors — never the legacy `output.Err*` helpers and never a final bare `fmt.Errorf`. AI agents parse the stderr envelope's `type` / `subtype` / `param` / `hint` fields to decide their next action; the full taxonomy lives in `errs/ERROR_CONTRACT.md`.
-
-Picking a constructor:
-
-| Failure | Constructor |
-|---------|-------------|
-| User flag/arg fails validation | `errs.NewValidationError(errs.SubtypeInvalidArgument, ...).WithParam("--flag")` |
-| Valid request, wrong system state | `errs.NewValidationError(errs.SubtypeFailedPrecondition, ...).WithHint(...)` |
-| Lark API returned `code != 0` | `runtime.CallAPITyped` (shortcuts) / `errclass.BuildAPIError` (raw responses) — never hand-build |
-| Network / transport failure | `errs.NewNetworkError(errs.SubtypeNetworkTransport, ...)` |
-| Local file I/O failure | `errs.NewInternalError(errs.SubtypeFileIO, ...)` — validate the path first (`validate.SafeInputPath` / `SafeOutputPath`) and use `vfs.*` |
-| Unclassified lower-layer error as final | `errs.NewInternalError(errs.SubtypeUnknown, ...).WithCause(err)` |
-| Lower layer already returned a typed error | pass it through unchanged — re-wrapping downgrades its classification |
-
-Signatures that are easy to guess wrong:
-
-- `runtime.CallAPITyped(method, url string, params map[string]interface{}, data interface{}) (map[string]interface{}, error)` — it performs the HTTP request itself and classifies `code != 0` into a typed error; just return the error it gives you.
-- Typed pass-through check: `if _, ok := errs.ProblemOf(err); ok { return err }` — `ProblemOf` returns `(*errs.Problem, bool)`, not a nilable pointer.
-- `.WithParam` exists only on `*errs.ValidationError`. `InternalError` / `NetworkError` have no param field — file or endpoint context goes in the message or `.WithHint(...)`.
-
-`forbidigo` + `lint/errscontract` reject the legacy `output.Err*` helpers, bare final `fmt.Errorf` / `errors.New`, and legacy envelope literals on migrated paths. Beyond what lint catches, three authoring conventions apply:
-
-- Preserve the underlying error with `.WithCause(err)` so `errors.Is` / `errors.Unwrap` keep working.
-- `param` names only the user input that actually failed. Recovery guidance goes in `.WithHint(...)`; machine-readable recovery fields (`missing_scopes`, `log_id`) carry server/system ground truth only — never caller-side guesses.
-- Error-path tests assert typed metadata via `errs.ProblemOf` (`category` / `subtype` / `param`) and cause preservation, not message substrings alone.
+`RunE` functions must return `output.Errorf` / `output.ErrWithHint` — never bare `fmt.Errorf`. AI agents parse stderr as JSON; bare errors break this contract.
