Normalize v1.1.0 release documentation

[GsCommand]

Motivation

• Normalize all release-facing documentation so v1.1.0 is clearly the current release and active schema line and v1.0.0 is historical/legacy only.
• Remove or reframe language that implies signed or cryptographic provenance and replace it with accurate checksum- and manifest-based integrity descriptions.
• Clarify that HTTPS hosting and IPFS pinning are separate distribution layers and that examples live in the repository (not necessarily in the npm package).

Description

• Rewrote and harmonized release messaging across README.md, SPEC.md, SCHEMAS.md, SECURITY_PROVENANCE.md, COMPLIANCE.md, GOVERNANCE.md, RESOLUTION.md, ONBOARDING.md, and CHANGELOG.md so v1.1.0 is the current release and v1.0.0 is historical.
• Replaced claims of “signed/cryptographic provenance” with precise language about checksums.txt, manifest.json, versioned schema paths, documented release metadata, and explicit statement that the repository does not currently publish signed release artifacts; updated receipt/provenance phrasing in schemas/docs to avoid overselling verification guarantees.
• Updated package and metadata files (manifest.json, package.json) to align descriptions and active_release metadata with the documentation normalization and added explicit npm-package notes in README.md stating that examples are not included in the npm package and that TypeScript examples are illustrative only.
• Cleaned .gitignore (removed stray NUL), converted RESOLUTION.md into a concise release log, and made other structural wording fixes to keep the tone precise and procedural while preserving all schema semantics, paths, and versions.

Testing

• Ran npm run validate which compiled all schemas and validated all example fixtures successfully.
• Ran npm run checksums:verify which verified file-level checksums in checksums.txt with all listed files reporting OK.
• Ran npm run test:smoke:pack (pack preflight) which completed successfully and produced a package tarball (commandlayer-commons-1.1.0.tgz).
