refactor: reposition repo as Agent Native Format

[shreyanshjain7174]

Renames the Go module and slug to agent-native-format and reframes the repo to lead with Agent Native Format (ANF).

What changed

• go.mod module path and all imports: Clawdlinux/agent-contract-protocol and the older ninevigil-acp slug -> Clawdlinux/agent-native-format. Build, vet, and tests pass.
• README h1 and GitHub About now lead with ANF, the token-minimal view format (FORMAT.md, pkg/anf, Kubernetes translator).
• The execution-contract runtime (formerly ACP) stays as a secondary component. Its code identifiers (acp-server, pkg/acp, ACP_AUTH_TOKEN) are unchanged.
• Superseded the 2026-06-16 naming record with a fresh ANF decision doc.
• Fixed stale clone path and release-tag notes.

Deliberately NOT in this PR (follow-ups, see naming-decision.md)

• Renaming acp-* code identifiers. Breaking, needs a decision on whether the runtime stays, renames, or is deprecated.
• Retitling the paper (paper/acp.*) and rebuilding as anf.pdf. It is an arXiv artifact and needs a chosen title.
• Cutting a fresh ANF-branded release.

Notes

• Releases already retitled ACP -> ANF (tags kept for link stability).
• Open issues Phase 0: validate Agent Contract Protocol premises #16-Phase 3: validate execution governance pain publicly #19 still frame the repo as Agent Contract Protocol and are now contradicted by this reposition. Will close them separately.

Pull request overview

This PR repositions the repository around Agent Native Format (ANF) by renaming the Go module/repo references from agent-contract-protocol to agent-native-format, while keeping the governed execution runtime (ACP) as a secondary component with unchanged identifiers.

Changes:

• Renamed the Go module path and updated Go import paths across runtime, translators, and tests.
• Reframed top-level docs/marketing content (README, landing page, blog post) to lead with ANF and clarified ACP’s role as the execution runtime.
• Added a new naming decision record documenting the ANF repositioning.
