chore(openspec): archive all completed changes, sync 14 new specs to library

Archived 4 completed OpenSpec changes (2026-04-02):
- phase-3-enterprise (100/100 tasks) — 6 Phase 3 capabilities synced
- devops-documentation (48/48 tasks) — 3 new + 1 merged capability
- bedroom-developer-docs (33/33 tasks) — 4 new capabilities synced
- engineering-docs (superseded by 2026-03-29 archive) — no tasks

Main spec library grows from 21 → 35 capabilities (+14 new):
federation, multi-tenancy, oidc, soc2, w3c-dids, webhooks,

+## ADDED Requirements
+
+### Requirement: Quick-start guide exists at docs/developers/quick-start.md
+The system SHALL provide a quick-start guide at `docs/developers/quick-start.md` that enables a bedroom developer to register their first agent and issue an OAuth 2.0 access token in under 5 minutes.
+
+#### Scenario: Developer completes quick-start from zero
+- **WHEN** a developer with no prior AgentIdP knowledge follows the quick-start guide
+- **THEN** they SHALL have a registered agent, a valid credential, and a working access token by the end
+
+### Requirement: Quick-start lists exact prerequisites
+The quick-start guide SHALL list all prerequisites at the top before any steps, so the developer knows what they need before starting.
+
+#### Scenario: Prerequisites are minimal and explicit
+- **WHEN** the developer reads the prerequisites section
+- **THEN** they SHALL see exactly: Docker (for running PostgreSQL and Redis) and curl (for API calls) — nothing else required
+
+### Requirement: Quick-start provides a working docker-compose startup command
+The quick-start guide SHALL include a single command to start the required infrastructure (PostgreSQL + Redis) using the project's `docker-compose.yml`.
+
+#### Scenario: Developer starts infrastructure
+- **WHEN** the developer runs the provided docker-compose command
+- **THEN** the guide SHALL confirm what services are started and what ports they run on
+
+### Requirement: Quick-start covers the full 4-step workflow
+The quick-start guide SHALL cover exactly these four steps in order, each with a working curl command and the expected response:
+
+1. Start the AgentIdP server
+2. Register an agent (`POST /agents`)
+3. Generate a credential (`POST /agents/{agentId}/credentials`)
+4. Issue an access token (`POST /token`)
+
+#### Scenario: Each step has a copy-pasteable curl command
+- **WHEN** the developer reads any step
+- **THEN** they SHALL find a complete curl command with real placeholder values they can substitute
+
+#### Scenario: Each step shows the expected JSON response
+- **WHEN** the developer runs a curl command from the guide
+- **THEN** the guide SHALL show them what a successful response looks like so they can verify their output
+
+### Requirement: Quick-start ends with a next-steps section
+The quick-start guide SHALL end with a "What's Next" section linking to: core-concepts.md, developer-guides.md, and api-reference.md.
+
+#### Scenario: Developer knows where to go after quick-start
+- **WHEN** the developer reaches the end of the quick-start
+- **THEN** they SHALL see at least 3 links to deeper documentation
