feat(v2): one-liner installer + zero-fork messaging cleanup

- Add install.sh: preflight-checked installer that pulls vanilla
  hermes-agent from PyPI, clones the repo, configures .env, installs
  deps. Idempotent, re-runnable.
- README: new 'One-line install' section with curl | bash command.
  Demote Manual install section to secondary path.
- Banner tightened: 'v2 — zero-fork. Clone, don't fork.'
- Remove 'Earlier versions required a fork' retrospective from banner;
  the fork is gone, we don't need to apologize for it.
- Model switch toast: drop 'enhanced fork' phrasing, use 'enhanced
  runtime' (the fork no longer exists as a distinct thing; vanilla
  provides the enhanced runtime).
- Update pinned-copy test accordingly.

One-liner for users:
  curl -fsSL https://raw.githubusercontent.com/outsourc-e/hermes-workspace/main/install.sh | bash

 ## 🚀 Quick Start
 
+### One-line install (recommended)
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/outsourc-e/hermes-workspace/main/install.sh | bash
+```
+
+This installs `hermes-agent` from PyPI, clones this repo, sets up `.env`, and installs deps. Then:
+
+```bash
+hermes gateway run                  # terminal 1
+cd ~/hermes-workspace && pnpm dev   # terminal 2
+```
+
+Open http://localhost:3000. That's it.

 Hermes Workspace works with any OpenAI-compatible backend. If your backend also exposes Hermes gateway APIs, enhanced features like sessions, memory, skills, and jobs unlock automatically.

 If you're pinned to an older `hermes-agent` version and missing endpoints, the workspace will degrade gracefully to **portable mode** with basic chat — upgrade upstream to restore full features.
