docs(readme): document OCP_PROXY_URL + CLAUDE_PROXY_PORT plugin reuse (per release_kit 5.5)

ocp-plugin/index.js hard-coded http://127.0.0.1:3456 since the plugin
was created. OCP server moved to 3478 default in v3.14+ as part of
the same wave that renamed the launchd label (dev.ocp.proxy). The
plugin never got the memo. Result: `/ocp usage` from OpenClaw bots
(e.g. the home Telegram bot 大内总管) hit the dead port 3456 and
returned "OCP error: fetch failed".

Fix:
- Default PROXY → http://127.0.0.1:3478
- Read OCP_PROXY_URL env (full URL) first
- Else read CLAUDE_PROXY_PORT env (port only, localhost assumed)
- Else fall back to the 3478 default

openclaw.plugin.json bumped (3.12.0 → 3.16.1) and configSchema
default updated. Plugin version now matches OCP version.

Top-level package.json bumped 3.16.0 → 3.16.1. CHANGELOG entry added.

Diagnostic trail: caught 2026-05-12 when home Telegram bot reported
"OCP error: fetch failed" against `/ocp usage`. Mac mini OCP service
was healthy on port 3478; lsof -iTCP:3456 had no listener; plugin
index.js had hardcoded 3456.

No cli.js citation needed: this is OCP-internal plugin code with no
corresponding cli.js operation.

 # Changelog
 
-## v3.16.0 — 2026-XX-XX (release date filled at tag time)
+## v3.16.1 — 2026-05-12
+
+### Fixes
+
+- **OCP plugin port lag** — `ocp-plugin/index.js` hard-coded `http://127.0.0.1:3456` while OCP server moved to 3478 in v3.14+. Result: `/ocp` slash commands in OpenClaw (e.g. `/ocp usage` from the home Telegram bot) returned "OCP error: fetch failed". Default is now `http://127.0.0.1:3478` and the plugin reads `OCP_PROXY_URL` env (full URL) or `CLAUDE_PROXY_PORT` env (port only) when set. `openclaw.plugin.json` `configSchema.proxyUrl.default` also updated and the plugin version bumped to `3.16.1`. Run `ocp update` to redeploy the plugin into `~/.openclaw/extensions/ocp/`.
