Replaces the single long-Notice failure UX with a kind-aware dispatcher
so users get actionable buttons instead of a wall of text.
- CliProcessError extends Error with a typed CliErrorDetails payload
(reason / pid / elapsed / idle / bytes / tails / exitCode / signal /
timeoutMs / idleTimeoutMs). All five runCli failure paths now throw
the typed error; message format is preserved so existing classifier
regex and tests still match.
- classifyGenerationError short-circuits on details.reason for the
deterministic cases (wall/idle-timeout → timeout, spawn/startup →
config, streams-unavailable → unknown). exit-nonzero falls through
so stderr-derived auth/rate-limit hints still classify correctly.
Duck-typed check avoids cli ↔ generation-job-manager circular import.
- New error-ui.ts dispatches by ErrorKind:
timeout (with details) → TimeoutDiagnosticsModal showing cmd, pid,
elapsed, idle, bytes, redacted stderr/stdout tail, plus copy /
open-settings / close buttons.
timeout (no details, e.g. API streaming) → actionable Notice.
auth/config → Notice + "Open Settings" CTA.
rate-limit → Notice + "Copy details".
schema → Notice + "Copy raw output" CTA.
unknown → unchanged legacy short Notice.
- main.ts handleGenerationError delegates to dispatcher; new
openPluginSettings() helper uses Obsidian's app.setting.openTabById.
- 21 i18n strings (zh + en) for all new UI labels and the modal copy.
- styles.css adds error notice + diagnostics modal styling.
- 7 new test assertions cover typed details on every failure path and
classifyGenerationError respecting structured reasons.
