refactor: package code organization wave 8 (#2252)
## Summary
Wave 8 of package code organization (plan:
`docs/plans/2026-07-14-001-refactor-package-code-organization-plan.md`),
after #2166.
### Peels
| New module | Parent |
|---|---|
| `app/api/board-workflows.ts` | `legacy.ts` |
| `app/api/remote.ts` | `legacy.ts` |
| `app/api/memory.ts` | `legacy.ts` |
| `types/docker-nodes.ts` | `types.ts` |
| `task-store/task-store-helpers.ts` | `remaining-ops-10.ts` (rename) |
### CI fix (main unblocker)
FN-8142 requires pi SDK **0.80.8+** (`ModelRuntime`,
`CredentialStore.list`). Floored `@earendil-works/pi-*` to `^0.80.8` so
lockfile resolves past 0.80.6.
Public import paths stay stable via re-exports.
### LOC
- `legacy.ts` ~10975 → ~10561
- `types.ts` ~7349 → ~6928
## Test plan
- [x] core / dashboard typecheck + eslint on peels
- [x] api-tasks (66)
- [x] CI merge gate (Lint / Typecheck / Build / Gate)
