SDK: Add ensureServer() for automatic server recovery

Add ensureServer() to SandboxProvider interface to handle cases where the
sandbox-agent server stops or goes to sleep. The SDK now calls this method
after 3 consecutive health-check failures, allowing providers to restart the
server if needed. Most built-in providers (E2B, Daytona, Vercel, Modal,
ComputeSDK) implement this. Docker and Cloudflare manage server lifecycle
differently, and Local uses managed child processes.

Also update docs for quickstart, architecture, multiplayer, and session
persistence; mark persist-* packages as deprecated; and add ensureServer
implementations to all applicable providers.

- `docs/agent-capabilities.mdx` lists models/modes/thought levels per agent. Update it when adding a new agent or changing `fallback_config_options`. If its "Last updated" date is >2 weeks old, re-run `cd scripts/agent-configs && npx tsx dump.ts` and update the doc to match. Source data: `scripts/agent-configs/resources/*.json` and hardcoded entries in `server/packages/sandbox-agent/src/router/support.rs` (`fallback_config_options`).
- Some agent models are gated by subscription (e.g. Claude `opus`). The live report only shows models available to the current credentials. The static doc and JSON resource files should list all known models regardless of subscription tier.
## Persist Packages (Deprecated)
- The `@sandbox-agent/persist-*` npm packages (`persist-sqlite`, `persist-postgres`, `persist-indexeddb`, `persist-rivet`) are deprecated stubs. They still publish to npm but throw a deprecation error at import time.
- Driver implementations now live inline in examples and consuming packages:
- SQLite: `examples/persist-sqlite/src/persist.ts`
- Postgres: `examples/persist-postgres/src/persist.ts`
- IndexedDB: `frontend/packages/inspector/src/persist-indexeddb.ts`
- Rivet: inlined in `docs/multiplayer.mdx`
- In-memory: built into the main `sandbox-agent` SDK (`InMemorySessionPersistDriver`)
- Docs (`docs/session-persistence.mdx`) link to the example implementations on GitHub instead of referencing the packages.
- Do not re-add `@sandbox-agent/persist-*` as dependencies anywhere. New persist drivers should be copied into the consuming project directly.
