docs(install): remove false symlink claim, fix Anonymous mode startup command

Three doc inaccuracies surfaced during fresh-state install testing on Pi231 +
MacBook (Round 1+2):

1. README §Server Setup claimed setup.mjs "Symlink `ocp` to /usr/local/bin for
   CLI access" — false. setup.mjs writes start.sh + plist/systemd unit but
   creates no PATH symlink. Removed the line; added a short PATH tip showing
   the user's options (manual symlink to ~/.local/bin or /usr/local/bin, or
   shell alias) right after the install summary.

2. README §Anonymous Access told users to run `ocp start` to enable the
   feature — there is no `ocp start` subcommand. Available commands are
   restart / stop / status / logs / keys / usage / update / lan / health /
   clear / settings (verified via `~/ocp/ocp` enumeration). Replaced with
   the correct flow: export PROXY_ANONYMOUS_KEY, then `node setup.mjs
   --bind 0.0.0.0 --auth-mode multi`.

3. The same paragraph implied that exporting PROXY_ANONYMOUS_KEY in an
   interactive shell is enough to enable anonymous access — but the running
   proxy is auto-started by launchd/systemd from the service unit's own
   env, not from the user's shell. Spelled this out and noted that if OCP
   was installed before exporting the env var, the user must re-run
   setup.mjs (idempotent) so the service unit env is refreshed, then
   `ocp restart`.

The PROXY_ANONYMOUS_KEY mechanism described becomes 100% accurate when
PR B (`fix/setup-inject-service-env`, sibling PR) lands; current setup.mjs
on main does not yet inject this env into the service unit.

Doc-only — no `server.mjs` change, no version bump, no `cli.js` citation
required.

 ### Server Setup
 
 > **Recommended:** Install OCP on a device that stays powered on — Mac mini, NAS, Raspberry Pi, or a desktop that doesn't sleep. This ensures all clients always have access.
 
 **Prerequisites:**
+- macOS or Linux (Windows is not supported — `setup.mjs` installs launchd / systemd auto-start)
 - Node.js 22.5+ (Node 23+ recommended — `node:sqlite` is fully stable without flags from 23.0; on 22.5–22.x it works behind `--experimental-sqlite`)
-- [Claude CLI](https://docs.anthropic.com/en/docs/claude-cli) installed and authenticated (`claude auth login`)
+- `git`
+- [Claude CLI](https://docs.anthropic.com/en/docs/claude-cli) — install and authenticate:
+  ```bash
+  npm install -g @anthropic-ai/claude-code
+  claude auth login   # prints a URL + code — open URL on any browser, sign in, paste code back

+#### Headless install notes
+
+OCP is designed for always-on devices that often don't have a desktop browser — Mac mini, NAS, Raspberry Pi, cloud VPS. The Claude CLI auth flow still works headless:
+
+**Option 1 — interactive OAuth over SSH (one-shot).** `claude auth login` prints a URL + 8-digit code. Open the URL on **any** device with a browser (your laptop, phone), sign in to your Anthropic account, and paste the code back into the SSH session. No browser needed on the server itself.
+
+**Option 2 — long-lived token (auth once, no re-prompts).**
+
+```bash
+claude setup-token   # subscription-backed long-lived token
+```
+
+Same Claude subscription as Option 1; the token is stored in Claude CLI's normal config location. Useful when you'd rather not redo the OAuth flow when sessions expire.
+
+If `claude auth login` errors out with something like `cannot open browser`, you've hit the same case — fall back to either option above.

 **Client side**: the anonymous key value is exposed via `GET /health` as the field `anonymousKey` (null when not set). Clients like `ocp-connect` can auto-discover and use it, so the end user doesn't need to get a personal key from the admin.
 
 **Security note**: setting this env var is an **opt-in** to public access — anyone who can reach your OCP endpoint can use it, up to any rate limits you configure. Don't enable this on internet-exposed OCP instances without additional protection.

 ## Troubleshooting
 
+### Setup fails with "claude: command not found"
+
+`setup.mjs` requires the Claude CLI to be on `PATH`. Install it via the [official guide](https://docs.anthropic.com/en/docs/claude-cli), confirm with `which claude`, then run `claude auth login` before re-running `node setup.mjs`.
+
+### Setup fails with "EADDRINUSE: port 3456 already in use"
+
+Something else is already bound to port 3456 — usually an old OCP instance. Check what:
+
+```bash
+lsof -nP -iTCP:3456 -sTCP:LISTEN
+```
+
+If it's an old OCP process, stop it before re-running setup:
+
+```bash
+ocp stop                                                # if the CLI is on PATH
+launchctl bootout gui/$(id -u)/dev.ocp.proxy            # macOS launchd fallback
+sudo systemctl stop ocp-proxy                           # Linux systemd fallback
+```
+
+### Setup fails with "node: command not found" or version error
+
+OCP requires Node.js 22.5+. Install:
+
+```bash
+brew install node          # macOS
+# Linux: see https://nodejs.org/en/download for current install commands
+```
+
+Confirm with `node --version` (should be ≥ v22.5).
