docs: concept annexation, provider/reference docs, ACT-1 groundwork

Mosaic concepts pages now own the adapted content; source/license
metadata under docs/reference/concepts. Adds ACT-1 agent-context
planning capture, pinned concept test package + preparation utility,
foundation observation notes (durability, evidence, federation,
onboarding, workflow), and the #1495 consolidation assessment.
TOOLS.md updated for the host-dev launcher.

+---
+
+# BOOT.md
+
+Add short, explicit startup instructions here. The bundled `boot-md` hook runs this file once per agent workspace every time the gateway starts, if the file exists and has non-whitespace content. Multiple agents sharing a workspace only trigger one run.
+
+The hook ships disabled. Enable it first:
+
+```bash
+openclaw hooks enable boot-md
+```
+
+This hook turns off normal final-response delivery. If a checklist item sends a message, use the message tool. Name a channel and a target in each call. Then reply with the silent token `NO_REPLY`, in any letter case.
