feat(showcase): nav separator + badge specimens; correct the §3 item-8 verdict (#1878)

Adds the two nav-affordance specimens to the showcase Analytics group
(`nav_sep_reports` separator + `badge: 'NEW'`/`badgeVariant: 'secondary'` on
Hours by Status) and corrects the naming-drift recheck, which twice published
a wrong verdict for this item.

The keys are LIVE. UnifiedSidebar delegates the whole app-navigation tree to
NavigationRenderer (UnifiedSidebar.tsx:437), which implements separator
(:906) and badge/badgeVariant (:983-985); processedNavigation only reorders
and pins, spreading every other key through. Browser-verified against an
UNMODIFIED objectui checkout: the divider draws and the NEW pill renders. No
objectui change was needed -- the port this PR was originally going to make
would have duplicated existing capability.

Both wrong rounds shared one shape: a strong negative claim ("the component
was deleted", "nobody imports it") resting on a search whose results were
silently truncated (head -3) or filtered (a pathspec glob that never matched
the nested path). The doc now carries a methodology note: a grep can only
prove presence; for "does authoring this key do anything", author it and look.

Showcase suite 58/58 green.

+feat(showcase): add nav `separator` + `badge`/`badgeVariant` specimens, and correct the §3 recheck's item-8 verdict (#1878)
+
+The recheck twice claimed these keys were unconsumed, both times from a faulty
+search. Settled empirically: `UnifiedSidebar` delegates the app-navigation tree
+to `NavigationRenderer`, which implements all three — the specimen renders
+against an unmodified objectui checkout. Docs/examples only; releases nothing.

-   prune.** The capability is fully built in `NavigationRenderer` (public export
-   + SDUI `navigation-renderer`); what is missing is the same three affordances
-   in `UnifiedSidebar`, the component that actually renders `app.navigation` in
-   the console. So an author's `badge: '3'` works if the nav is rendered through
-   the SDUI component and silently vanishes in the console shell — a
-   *surface-dependent* no-op, the hardest kind to diagnose. Disposition: port the
-   three branches into `UnifiedSidebar` (reference implementations already exist
-   at `NavigationRenderer.tsx:906,983-985`), not prune the keys.
 5. **`skill.permissions` has no gate** — mis-filed as naming drift; it is an
    aspirational-config item (§4). The ledger marks it `live` on the evidence of a
    *preview renderer* while the identically-unenforced `tool.permissions` is
    `dead` + `authorWarn`. An author writing `skill.permissions` gets silence
    where they should get a warning.

    its sources from the LLM tool call, not from the authored block. Wire or mark

+**Round 1.** `git grep -rln "NavigationRenderer" | head -3` returned three
+CHANGELOG/ROADMAP hits, and that was read as "the component was deleted." The
+`head -3` had truncated the real source hit further down the alphabet.
+→ Published claim: *"NavigationRenderer no longer exists."* **False.**
+
+**Round 2.** `git grep -n "NavigationRenderer" -- 'packages/*/src' 'apps/*/src'`
+returned nothing, and that was read as "the component is an orphan, nobody
+imports it." The pathspec glob never matched the nested
+`packages/app-shell/src/layout/UnifiedSidebar.tsx`.
+→ Published claim: *"live nav renders no badge; port the branches."* **Also false.**
+
+**Round 3 (settled).** Author a specimen, boot the real stack, look at it. The
+separator drew and the badge rendered — against an *unmodified* renderer.
+
+Both wrong rounds share one shape: **a strong negative claim ("X does not
+exist", "nobody consumes X") resting on a search whose result set was silently
+truncated or filtered.** A grep can only ever prove presence; absence needs
+either an exhaustive search you have verified is exhaustive, or — better, and
+decisive here — a runtime observation. For liveness work specifically: when the
+question is "does authoring this key do anything", the cheapest *sound* answer
+is usually to author it and look, not to grep for readers.
