Yaowei Zheng d4faee3a1e Changelog, dev startup, README, AgentHub 0.4.0, model catalog, and landing site (#7)
Branch-length batch covering tooling, the model layer, the Web App and the public
surfaces. Highlights:

- Changelog: a per-release `changelog/<version>/` tree, grouped by the surface each
  change touches, with a root CHANGELOG.md holding one line per release.
- Dev startup: `scripts/dev-prebuild.mjs` serializes the skills+core prebuild behind a
  lock and keeps `pnpm install` current; `pnpm dev` runs server+web together.
- AgentHub 0.3.3 -> 0.4.0: OmniMessage complete payloads carry one opaque `fidelity`
  object in place of item-level `signature`/`phase`, threaded verbatim through Trace,
  replay and resume; malformed classification adapted to the new error types.
- Model layer: a model is always referenced by an explicit `(provider, model_id)` pair.
  The provider is never inferred, guessed or defaulted -- both the catalog inference and
  the unique-match config resolution are gone, and CLI, SDK, server routes and
  run_subagent all require the complete pair. Catalog gains the Qwen Token Plan, Qwen
  Pay-As-You-Go and Fireworks AI gateways, plus an expanded OpenRouter group.
- Web App: catalog preset sync and per-group speed test on the Models page, positional
  slash commands, a markdown renderer, skill-library update reminders, and a vertically
  centred draft page whose upward menus size themselves to the room available.
- Public surfaces: restructured READMEs, the penguin.ooo landing site and blog, refreshed
  benchmark results for both suites, and the demo videos playing on the landing page.

Includes the fixes from a full review of the branch: 23 confirmed findings, among them a
provider-inference bug that could send one vendor's API key to another vendor's endpoint,
and an Escape handler that destroyed the composer's contents unrecoverably.

Verified on the branch head: pnpm test (1127 passing, 7 packages), pnpm typecheck and
pnpm format:check clean, Playwright e2e 14/14.

/**
* Render the README "build an Agent app in one sentence" finished-product shot.
*
* The image shows the RESULT of the example — a Claude Code docs-expert RAG app —
* rather than the build conversation: rag-app-mockup.html is a static, dependency-free
* mockup of the generated app's UI (per the web-design skill's Penguin visual language),
* captured per language (zh / en) and theme (light / dark) into assets/readme/ at the
* repo root as rag-app-<lang>-<theme>.webp (README.md uses en, README.zh.md uses zh).
*
* Prereqs: Playwright's chromium only (no server, no build). Run:
* `node scripts/capture-readme-demo.mjs [--png-dir <dir>]` (--png-dir also saves
* lossless PNG copies, handy for reviewing the shots).
