### Documentation overhaul

Complete rewrite of the Hexel Studio documentation.

* Accurate API paths, error codes, SDK methods, and enums verified against the codebase
* Auth0-style narrative added throughout — plain-English explanations before technical detail
* New sections: Data Platform, Orchestration, Tool Gateway, IAM, Observability, Billing
* Correct base URL for all API calls (`api.hexelstudio.com/compute/v1`)
* Navigation restructured with product-named tabs and Lucide icons

### Hexel Studio Launch

Hexel Studio is generally available — the infrastructure platform for AI agents in production.

**Compute**

* Sandboxes: isolated, single-use execution environments drawn from a warm pool. Allocate in milliseconds, run Python code or shell commands, release when done.
* Agent hosting: register a Docker image, deploy it, and receive a permanent endpoint. Same configuration always produces the same URL. Instances run always-on with CPU throttling; idle cost is near zero.
* Instances: four compute tiers (`micro`, `standard`, `large`, `gpu`). Deploy via `POST /compute/v1/agents/{id}/instances` or `hexel compute instance deploy`.
* Skills: publish reusable capabilities to the platform via `/compute/v1/skills`.
* Sessions and filesystems: group runtime resources and attach persistent storage across sandbox calls.

**Data Platform**

* Knowledge stores: ingest documents (PDF, DOCX, TXT, MD, HTML, JSON, CSV) or connect an S3 datasource. Content is chunked, embedded, and made searchable via semantic search.
* Memory: scoped memory stores with automatic expiry — TASK (24h), SESSION (8h), AGENT (1 year), WORKSPACE (1 year).
* Connectors: S3 datasource with configurable sync schedule, pause/resume, and sync history.
* Context bundles: assemble grounded context from knowledge and memory for a specific run.
* All Data Platform APIs at `api.hexelstudio.com/data/v1/`.

**Orchestration**

* Tasks: submit a goal (`input`) to a fleet. The platform plans it, executes it across agents, gates sensitive actions with approvals, and streams events over SSE.
* Fleets: group agents with runtime configuration (deployment mode, routing policy, capacity profile, isolation profile, egress policy).
* Approvals: gate task execution with human or policy review. Pending approvals expire after 24 hours.
* Policies: define ALLOW / DENY / REQUIRE\_APPROVAL rules evaluated against task context.
* Streaming: real-time SSE events (`task.submitted`, `task.state`, `task.complete`, `runtime.delta`, and more). Full replay from recorded execution.
* Orchestration APIs at `api.hexelstudio.com/orchestrator/v1/`.

**Tool Gateway**

* 6 toolkits at launch: Gmail, Google Sheets, Slack, GitHub, Jira, WhatsApp (82 tools total).
* Connect accounts via managed OAuth; credentials are encrypted at rest and never returned by the API.
* Bind toolkits to agents; the gateway resolves credentials automatically at execution time.
* Execution modes: synchronous, asynchronous, batch, preflight. Idempotency keys for safe retries.
* 20 trigger types across Google Sheets, Gmail, GitHub, Slack, WhatsApp, and Jira for event-driven automation.
* Webhook subscriptions with signature verification for execution and trigger notifications.
* MCP server support for custom and generated tool integrations.
* Tool Gateway APIs at `api.hexelstudio.com/tools/v1/`.

**SDKs & CLI**

* Python SDK (`pip install hexel`): compute, orchestration, tools, agent runtime, and LLM instrumentation (OpenAI, Anthropic).
* TypeScript SDK (`npm install hexel-sdk`): compute, orchestration, and tools.
* CLI (`hexel`): infrastructure and operations — compute, fleets, tasks, tools, policies, approvals.
* API key and OAuth client credentials authentication via STS (15-minute tokens, 30-day refresh).

**Platform**

* Organizations, workspaces, and environments with complete resource isolation.
* Role-based access control with least-privilege RBAC permissions.
* Service users, API keys, and OAuth access clients.
* Token exchange via STS (`sts.hexelstudio.com`).

**API Reference**

* Interactive playground for all endpoints.
* OpenAPI specifications.
* Code examples in Python, TypeScript, Go, and curl.
