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: Local Development
+summary: Set up Paperclip for local development
+---
+
+Run Paperclip locally with zero external dependencies.
+
+## Prerequisites
+
+- Node.js 20+
+- pnpm 9+
+
+## Start Dev Server
+
+```sh
+pnpm install
+pnpm dev
+```
+
+This starts:
+
+- **API server** at `http://localhost:3100`
+- **UI** served by the API server in dev middleware mode (same origin)
+
+No Docker or external database required. Paperclip uses embedded PostgreSQL automatically.
+
+## One-Command Bootstrap
+
+For a first-time install:
+
+```sh
+pnpm paperclipai run
+```
+
+This does:
+
+1. Auto-onboards if config is missing
+2. Runs `paperclipai doctor` with repair enabled
+3. Starts the server when checks pass
+
+## Tailscale/Private Auth Dev Mode
+
+To run in `authenticated/private` mode for network access:
+
+```sh
+pnpm dev --tailscale-auth
+```
+
+This binds the server to `0.0.0.0` for private-network access.
+
+Allow additional private hostnames:
+
+```sh
+pnpm paperclipai allowed-hostname dotta-macbook-pro
+```
+
+## Health Checks
+
+```sh
+curl http://localhost:3100/api/health
+# -> {"status":"ok"}
+
+curl http://localhost:3100/api/companies
+# -> []
+```
+
+## Reset Dev Data
+
+To wipe local data and start fresh:
+
+```sh
+rm -rf ~/.paperclip/instances/default/db
+pnpm dev
+```
+
+## Data Locations
+
+| Data | Path |
+|------|------|
+| Config | `~/.paperclip/instances/default/config.json` |
+| Database | `~/.paperclip/instances/default/db` |
+| Storage | `~/.paperclip/instances/default/data/storage` |
+| Secrets key | `~/.paperclip/instances/default/secrets/master.key` |
+| Logs | `~/.paperclip/instances/default/logs` |
+
+Override with environment variables:
+
+```sh
+PAPERCLIP_HOME=/custom/path PAPERCLIP_INSTANCE_ID=dev pnpm paperclipai run
+```
