OpenClaw: update hello-world post with new capabilities (#3)

Updates `thoughts/openclaw.md` to reflect Angela/OpenClaw’s current capabilities (repo ops, browser + web research, messaging, cron reminders, vision/image analysis, paired-device actions, voice notes on request).

Also resolves manifest/tags for `thoughts/.wp-materialize.json`.

Validation: `wp-materialize local` export succeeded.
