docs(sdk): add published install commands

[vincentkoc]

What Problem This Solves

The SDK documentation still says the packages are unpublished even though
@openclaw/krillswitch-core and @openclaw/krillswitch-react v0.0.1 are now
available from npm.

Why This Change Was Made

This replaces the pre-publication caveats with copyable install commands,
records the exact initial SDK release, and keeps the root release guidance
aligned with the published packages.

User Impact

Developers can install either SDK directly from npm without mistaking the
packages for workspace-only artifacts.

Evidence

• node scripts/build-docs-site.mjs (17 pages built)
• git diff --check
• Clean registry install of both v0.0.1 packages passed runtime imports,
  React-free server import, TypeScript, and dependency deduplication.
• SDK release workflow:

• SDK release:
  https://github.com/openclaw/krillswitch/releases/tag/sdk-v0.0.1
