feat(sealed): sealed journey + docs (§11 tail M5)

- tests/sealed.rs: a group declares a sealed [[routes]] template; a descendant
  that suppresses it still serves the path, apply warns "sealed — no effect",
  routes ls --group shows sealed=true, and sealing an [app] route is rejected.
- docs: §4.5 trust-model callout + CLAUDE.md move `sealed` from Deferred to
  implemented — group templates are advisory-by-default *unless* sealed.

+//! §11 tail — `sealed` (non-suppressible) group templates, end to end via
+//! `pic`. A group declares a **sealed** `[[routes]]` template; a descendant app
+//! that applies a `[suppress] routes=[...]` for it STILL serves the inherited
+//! path (the rebuild keeps a sealed row), the apply emits an ineffective-suppress
+//! warning, and `pic routes ls --group` shows `sealed = true`. Sealing an
+//! `[app]` route is rejected — sealing marks a *group* template, and an app
+//! route is never inherited.
+//!
+//! The repo-layer proof (a sealed trigger + route survive suppression while an
+//! unsealed sibling is declined) lives in
+//! `manager-core/tests/sealed_templates.rs`; this journey exercises the
+//! authoring + the orchestrator dispatch path the operator uses.
