chore(v1.1.3-modules): version bumps + CHANGELOG + blueprint touch-up

- Workspace `1.1.2` → `1.1.3` (`Cargo.toml`).
- Dashboard `0.8.0` → `0.9.0` (`package.json`).
- CHANGELOG: full v1.1.3 entry covering ScriptKind, ModuleSource,
  PicloudModuleResolver, the two caches, dep-graph table, route +
  trigger module rejection, the latent cross-app trigger gap that
  this release closes, migrations 0015/0016, and downgrade caveats.
- Blueprint: mark the "Can scripts `import` Rhai modules?" question
  as resolved; one-line pointer to the v1.1.3 semantics.

+- [x] **Module loading**: Scripts can `import "<name>" as <alias>;` other scripts in the same app (v1.1.3 — `scripts.kind = 'module'`). Per-app, cross-app isolated, cache-invalidated on `updated_at` change. External (off-platform) modules remain out of scope.
