Merges FN-4015 to add stale module-resolution incident detection and self-healing in the engine (`transient-error-detector.ts`, `self-healing.ts`) with mobile regression coverage for the shared `AgentErrorDetailsModal` layout.
Fusion-Task-Id: FN-4015
pi-ai's openai-codex-responses provider surfaces ChatGPT-plan WebSocket
drops as bare "WebSocket error" / "WebSocket closed <code>". The
underlying ErrorEvent.error is dropped by extractWebSocketError (it only
inspects event.message), so the cause is gone by the time we see it.
The engine then propagated these as fatal failures instead of retrying
a transient network blip.
- Add WebSocket patterns to TRANSIENT_ERROR_PATTERNS so the executor's
existing transient retry path picks them up.
- Tag the model id onto the thrown error and emit a structured warn in
promptSessionAndCheck so future drops can be triaged by transport.

- Move all co-located *.test.* files into sibling __tests__/ directories so the
layout is consistent across packages (159 renames + content-rewrite moves).
Updates relative imports, vi.mock specifiers, and __dirname/import.meta.url
path resolutions where tests read fixtures from disk.
- Drop tracked tsc-emit alongside engine .ts sources (auth-storage/logger/
skill-resolver/context-limit-detector/pi.{js,d.ts,*.map}). These were
accidentally committed in a merge and the stale pi.js was masking a real
test-mock vs source mismatch (tests imported "../pi.js" and vite preferred
the stale build over pi.ts).
- Add packages/engine/.gitignore to block future src/*.{js,d.ts,map}.
- Refactor plugin pi-module seams (openclaw/paperclip/hermes) to ESM-import
createFnAgent / promptWithFallback / describeModel from @fusion/engine
instead of require()-ing packages/engine/src/pi.js. Adds @fusion/engine to
the two plugin package.jsons that were missing it; exports describeModel
from the engine public API.
- Fix engine test mocks now that they run against current pi.ts: add
ModelRegistry.create static to mocks in pi.test.ts and pi-create-fn-agent
.test.ts; switch three boundary-result toEqual assertions to toMatchObject
so the new content/isError fields don't trip exact-match comparison.
