docs(skill): clarify license duality, bump to 2.3.2

ClawHub platform enforces MIT-0 on all skill descriptors and ignores
per-skill license overrides. Remove the unused 'license' field from
frontmatter (no-op) and add an explicit note in the Security & Trust
section: the ClawHub descriptor is MIT-0, but the underlying npm
packages (@actalk/inkos, @actalk/inkos-core, @actalk/inkos-studio) are
AGPL-3.0-only and running/redistributing InkOS is governed by AGPL.

 ## Security & Trust
 
-- **License**: AGPL-3.0-only (all packages). Full source on GitHub for auditability.
+- **License**: the ClawHub skill descriptor is MIT-0 per platform policy, but the underlying `@actalk/inkos`, `@actalk/inkos-core`, and `@actalk/inkos-studio` npm packages are **AGPL-3.0-only**. Running InkOS and distributing modified versions are governed by AGPL. Full source on GitHub for auditability.
 - **No install hooks**: npm package has no `preinstall`/`postinstall`/`install` scripts. Install is inert.
 - **Local-only file I/O**: all read/write stays inside the project directory (`books/*`, `inkos.json`, `inkos.log`). No writes outside the working directory.
 - **No telemetry**: InkOS does not phone home, collect usage stats, or ship any data to InkOS-controlled servers. The only outbound traffic is to the LLM provider endpoint you explicitly configure.
