Declare agent-sdk as canonical developer SDK in site docs

[GsCommand]

Decision: commandlayer/agent-sdk is the canonical forward SDK repo for the current CLAS Trust Verification work.

Rationale:

• commandlayer-org already references @commandlayer/agent-sdk in developer-facing quickstarts/docs.
• agent-sdk contains the active CLAS Trust Verification work: trust schemas, receipt alignment, verifierUrl support, capability normalization, and validation helpers.
• commandlayer-org is self-contained at runtime and does not need to import either SDK; it only needs docs/links to point to the correct developer SDK.
• commandlayer/sdk can remain a separate legacy/broader SDK repo until a dedicated migration/archive decision is made.

Tasks:

1. Audit commandlayer-org pages for SDK links/references.
2. Ensure developer-facing links point to:
   https://github.com/commandlayer/agent-sdk
3. Ensure install snippets use:
   npm install @commandlayer/agent-sdk
4. Ensure import snippets use:
   import { CommandLayer } from "@commandlayer/agent-sdk"
5. Do not point primary docs to commandlayer/sdk unless explicitly labeled legacy/old/broader SDK.
6. Do not change runtime verifier code.
7. Do not change nav except where already requested separately.

Pages likely affected:

• public/sdk-records.html
• public/docs/wrap-your-agent.html
• public/index.html
• public/how-it-works.html
• README.md if present

Report:

• files changed
• links updated
• any remaining references to commandlayer/sdk
• any intentional legacy references kept
