fix(scripts): default CLAUDE_PROXY_PORT to 3456 (completes v3.16.2 revert) (#97)

Three places in scripts/ still defaulted to 3478 after v3.16.2's
plugin / manifest / README / plist revert:

  scripts/upgrade.mjs:137
  scripts/doctor.mjs:84
  scripts/doctor.mjs:205

These were the residual cascade source for the port-drift bug originally
caused by the PR #71 dogfood accident on 2026-05-08 (see
~/.cc-rules/memory/learnings/subagent_setup_mjs_prod_host_collision.md
and v3.16.2 CHANGELOG entry).

Every `ocp doctor` / `ocp upgrade` invocation without an explicit
`CLAUDE_PROXY_PORT` in env probed port 3478 — got "OCP not responding"
against a healthy 3456 instance — and on the maintainer's host this
cascaded into wrong baseUrl writes for the OpenClaw `claude-local`
provider, taking out the OpenClaw Telegram agent ("大内总管") on
2026-05-13.

This change is the smallest possible: three string literals
`"3478"` → `"3456"`, aligning unset-env defaults with `server.mjs:126`.
Env-set users are unaffected (env precedence is unchanged).

cli.js: not applicable — this is a scripts/ change, not server.mjs.
ALIGNMENT.md hard-requirements (cli.js citation, blacklist CI,
independent reviewer) target server.mjs; this PR honors the SPOT
spirit by ending the literal-port drift across the codebase.

Bumps to v3.16.3. CHANGELOG entry added.

+## v3.16.3 — 2026-05-13
+
+### Fixes — completes v3.16.2 port-drift revert
+
+v3.16.2 reverted the plugin / `openclaw.plugin.json` / README / Mac mini
+plist back to `3456` (the historical source default since `593d0dc`), but
+missed three places in `scripts/` that still defaulted to `3478`. Those
+three lines were the residual cascade source: every time `ocp doctor` or
+`ocp upgrade` ran without `CLAUDE_PROXY_PORT` in the env, they probed
+`3478`, reported "OCP not responding" against a healthy 3456 instance,
+and (in the case of OpenClaw sync follow-ups on the maintainer's host)
+re-introduced 3478 into downstream config.
+
+Changes:
+
+- `scripts/upgrade.mjs:137` — default port `3478` → `3456`.
+- `scripts/doctor.mjs:84` — default port `3478` → `3456`.
+- `scripts/doctor.mjs:205` — default port `3478` → `3456`.
+
+No behavior change for users who set `CLAUDE_PROXY_PORT` explicitly; env
+still takes precedence. The fix only affects the unset-env fallback,
+which now matches `server.mjs:126` and the rest of the codebase.
+
+Test plan: existing `test-features.mjs` cases that pin
+`CLAUDE_PROXY_PORT=3478` continue to pass — they use the env path, not
+the default.
