Pull request overview
This PR updates error type-checking patterns across the codebase to use the Go 1.26+ typed helper errors.AsType[T](err) instead of errors.As(err, &target), and aligns documentation/tests with the new idiom.
Changes:
- Replaced
errors.Ascall sites witherrors.AsType[T]in runtime code paths and tests. - Updated
LimitErrordocumentation to demonstrate the new typedAsTypepattern. - Simplified several error-handling blocks by removing now-unnecessary target variable declarations.

Run the recovery subtests sequentially so the relayer has time to relaunch between plugin-killing limit hits, instead of racing multiple parallel calls against a connection that is still closing.

- The test assigns limitErr and then uses
_ = limitErronly to avoid an unused-variable compile error. Since the value isn't asserted on, this can be simplified by discarding it in the AsType assignment.
limitErr, ok := errors.AsType[LimitError](err)
require.True(t, ok)
_ = limitErr
_, ok = errors.AsType[LimitError](fmt.Errorf("wrapped: %w", err))
require.True(t, ok)
