feat: reorder agents and remove NanoClaw (#1477)

* feat: add ZeroClaw agent (14.9k stars, native OpenRouter support)

Add ZeroClaw — a Rust-based autonomous AI assistant framework by
Harvard/MIT/Sundai.Club communities — across all 8 clouds.

Scripts: local, hetzner, digitalocean, fly, aws, gcp, daytona, sprite
Install: bootstrap.sh with --install-rust + --install-system-deps
Config:  zeroclaw onboard --provider openrouter (via agent_configure)
Env:     OPENROUTER_API_KEY + ZEROCLAW_PROVIDER=openrouter (native support)
Launch:  zeroclaw agent

Note: ZeroClaw compiles from Rust source (~5-10 min build time).
A build-time warning is shown to set expectations.

Also update test/mock-curl-script.sh to stub zeroclaw install URLs and
add zeroclaw to mock agent binaries in test/mock.sh.

Bump CLI version 0.5.8 → 0.5.9.

* feat: reorder agents and remove NanoClaw

New agent order: claude → openclaw → zeroclaw → codex → opencode → kilocode

- Remove NanoClaw (8 scripts + manifest entry + matrix entries + README row)
- Reorder manifest.json agents section to match new order
- Reorder matrix entries by cloud (local/hetzner/fly/aws/daytona/digitalocean/gcp/sprite)
  with agents in new order within each cloud block
- Update README matrix table row order
- Update test/mock.sh mock agent binary list to match
- Bump CLI version 0.5.9 → 0.5.10
