Add agent-sdk release-readiness audit report

[GsCommand]

Motivation

• Perform a release-readiness audit of the agent SDK after canonical runtime-core alignment to surface packaging, versioning, and build/test concerns for an upcoming npm release.
• Record actionable findings and blockers so maintainers can remediate packaging and CI issues before publishing.

Description

• Add AUDIT-agent-sdk-release-readiness.md containing a structured audit that inspects package.json (version, files, main, types), README examples, schema packaging, and references to receipt/proof fields.
• Report that the package version is 1.1.0, there is no exports map, the files allowlist includes dist/examples but does not explicitly include schema JSON assets, and npm pack --dry-run omits schema JSONs from the tarball.
• Recommend a minor version bump to 1.2.0 (not 2.0.0) unless introducing an exports map causes breaking deep-imports, and list release blockers for maintainers to address.
• Note scope: the requested commandlayer/agent-sdk path was not present, so the audit was executed against the repository root package @commandlayer/agent-sdk.

Testing

• Ran npm install which failed with a 403 Forbidden fetching require-from-string@2.0.2, preventing a clean dependency install.
• Ran npm run build which failed due to unresolved TypeScript modules/types (downstream of the failed install).
• Ran npm test which failed because pretest runs the build and the build failed.
• Ran npm pack --dry-run which succeeded and produced a tarball listing the packaged dist artifacts, README.md, LICENSE, and package.json but not the schema JSON assets.
