fix: restore docs deleted in v0.2.3 release, add Paperclip branding

- Restored docs/ directory that was accidentally deleted by `git add -A`
  in the v0.2.3 release script
- Replaced generic "P" favicon with actual paperclip icon using brand
  primary color (#2563EB)
- Added light/dark logo SVGs for Mintlify navbar (paperclip icon + wordmark)
- Updated docs.json with logo configuration for dark/light mode
- Fixed release.sh to stage only release-related files instead of `git add -A`
  to prevent sweeping unrelated changes into release commits

+title: Approvals
+summary: Governance flows for hiring and strategy
+---
+
+Paperclip includes approval gates that keep the human board operator in control of key decisions.
+
+## Approval Types
+
+### Hire Agent
+
+When an agent (typically a manager or CEO) wants to hire a new subordinate, they submit a hire request. This creates a `hire_agent` approval that appears in your approval queue.
+
+The approval includes the proposed agent's name, role, capabilities, adapter config, and budget.
+
+### CEO Strategy
+
+The CEO's initial strategic plan requires board approval before the CEO can start moving tasks to `in_progress`. This ensures human sign-off on the company direction.
+
+## Approval Workflow
+
+```
+pending -> approved
+        -> rejected
+        -> revision_requested -> resubmitted -> pending
+```
+
+1. An agent creates an approval request
+2. It appears in your approval queue (Approvals page in the UI)
+3. You review the request details and any linked issues
+4. You can:
+   - **Approve** — the action proceeds
+   - **Reject** — the action is denied
+   - **Request revision** — ask the agent to modify and resubmit
+
+## Reviewing Approvals
+
+From the Approvals page, you can see all pending approvals. Each approval shows:
+
+- Who requested it and why
+- Linked issues (context for the request)
+- The full payload (e.g. proposed agent config for hires)
+
+## Board Override Powers
+
+As the board operator, you can also:
+
+- Pause or resume any agent at any time
+- Terminate any agent (irreversible)
+- Reassign any task to a different agent
+- Override budget limits
+- Create agents directly (bypassing the approval flow)
