Tyler Slaton ebad989855 chore(showcase/langgraph-python): manifest, runtime, e2e, cleanup ...

Cross-cutting changes that don't belong with any one demo: manifest +
landing-page tags, runtime route adjustments, e2e + QA notes that
follow the demo renames, and a few small cleanups.

Manifest (manifest.yaml + src/app/page.tsx tag labels):
- Naming convention: every demo uses `Thing: Subthing` (Generative UI:
  Tool Rendering - Default / Custom Default / Specific; Open Generative
  UI: Default / Advanced; Shared State: Streaming / Read + Write;
  Reasoning: Default / Custom; Frontend Tools: In-App Actions / Async;
  Human in the Loop: In-chat / In-App / Interrupt based; Chat
  Customization: CSS / Slots; Headless UI: Simple / Complete).
- Retags: Auth → `platform`; HITL Step Selection + Interrupt-based →
  `interactivity`; Reasoning Default + Custom → `chat-ui`; Generative
  UI: Tools → `generative-ui`.
- Renames: Readonly State (Agent Context) → Frontend Context Sharing.
- HITL slot points at /demos/hitl-in-chat (working
  useHumanInTheLoop+interrupt path) instead of the previous
  /demos/hitl that had no backend `interrupt()` calls.
- Highlight paths corrected for the rebuilt headless demos (root-level
  paths replaced with hooks/, chat/, tools/, attachments/ subdirs).
- Descriptions rewritten where they had drifted from the implementation
  (gen-ui-agent: dropped useCoAgentStateRender claim;
  headless-simple: shadcn primitives, not raw Tailwind;
  headless-complete: enumerates the actual hooks wired).

Runtime / route:
- src/app/api/copilotkit/route.ts — 30 agents registered (incl. the
  reasoning-custom rename from agentic-chat-reasoning).
- copilotkit-mcp-apps/route.ts replaced with [[...slug]]/route.ts so v2
  subpath POSTs (/v2/agent/run) resolve.
- src/app/api/copilotkit-voice/[[...slug]]/route.ts — env var standardized
  (was `AGENT_URL || LANGGRAPH_DEPLOYMENT_URL`, now matches the rest
  of the showcase with just LANGGRAPH_DEPLOYMENT_URL); trailing `/`
  removed from deploymentUrl.

Tests / QA:
- e2e specs renamed and paths updated for the demo renames.
- qa notes for a2ui-fixed-schema (booked-state checklist removed) and
  byoc-json-render (Wave 4a residue removed).
- docs-links.json key renamed for reasoning-custom.

Cleanup:
- Removed remaining stub agent.py files in demo dirs (real graphs in
  src/agents/); removed dead beautiful-chat/components/headless-chat.tsx
  (zero importers); removed [A2UI-DEBUG] / [A2UI-RESPONSE] print
  statements from beautiful_chat.py; gpt-5.4-mini → gpt-5-mini typo
  fix in beautiful_chat.py:249 (would have 4xx'd every model call);
  stripped iframe-restriction LLM-prompt copy bleed from
  open-gen-ui-advanced suggestion titles.

The convention pass that ran across ~28 demos earlier in this branch is
already reflected in their per-demo commits — every page.tsx reads as
imports + provider + suggestions hook + JSX, with `useConfigureSuggestions`
extracted to a sibling suggestions.ts.
