Subject: [PATCH] v3.4.0: subscription backend (Claude Code / Codex / Grok
 logins)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Rust harness can now use models two ways:
- API: provider API key (OpenAI-compatible HTTP) — existing path
- Subscription: drive the locally-installed agentic CLI login directly, no API
  key (anthropic→claude, openai→codex, xai→grok)

- models.rs: ChatClient::chat_cli spawns the CLI (stdin prompt), cli_binary_for
  + installed_cli_backends + binary_in_path PATH detection
- pool.rs: ModelPool::with_auth(subscription); one() routes per model
- types/CLI: RunConfig.subscription + `run --subscription` flag
- web: /api/run honors "subscription"; /api/info reports detected cli_backends;
  SPA gets a "Use subscription" toggle

Verified live: `run --subscription --model anthropic:claude-haiku-4-5` drove the
Claude subscription end-to-end (recon + agent + vote) with no API key set.
