[codex] migrate npm scope to threadplane

[blove]

Summary

• Migrate current npm/package specifiers from @ngaf/* to @threadplane/*, including public package manifests, workspace aliases, lockfile entries, docs, examples, cockpit demos, and generated public agent context.
• Rename current NGAF-branded code/prose to Threadplane where it is not a sticky public contract, including chat demo build flags, localStorage keys, telemetry Angular provider symbols, and smoke scaffolding.
• Update the first @threadplane release runbook for manual npm publication before OIDC trusted publishing can be configured.

Sticky identifiers intentionally preserved

• NGAF_TELEMETRY_* env vars remain as the telemetry opt-out/ingest contract.
• ngaf:* telemetry events remain as the analytics taxonomy contract.
• --ngaf-chat-* CSS custom properties remain as the public chat theming API.
• Stripe metadata keys ngaf_tier_slug / ngaf_billing_cycle remain for existing products.
• Historical changelog/spec references are left intact.

Validation

• node --check examples/chat/smoke/cli.mjs
• npx nx run-many -t lint,test,build --projects=chat,langgraph,ag-ui,render,a2ui,licensing,telemetry --skip-nx-cache
• node libs/telemetry/scripts/apply-install-telemetry.mjs dist/libs/chat dist/libs/langgraph dist/libs/ag-ui dist/libs/render dist/libs/a2ui dist/libs/licensing
• node libs/telemetry/scripts/verify-install-telemetry.mjs dist/libs/chat dist/libs/langgraph dist/libs/ag-ui dist/libs/render dist/libs/a2ui dist/libs/licensing dist/libs/telemetry
• node libs/telemetry/scripts/smoke-install-telemetry.mjs dist/libs/chat dist/libs/langgraph dist/libs/ag-ui dist/libs/render dist/libs/a2ui dist/libs/licensing dist/libs/telemetry
• node scripts/verify-release-versions.mjs --tag v0.0.46
• npx nx release publish --groups=publishable --dry-run
• npx nx run examples-chat-smoke:verify-local
• npx nx run examples-chat-angular:lint --skip-nx-cache
• npx nx run examples-chat-angular:test
• npx nx build examples-chat-angular --configuration=production --skip-nx-cache
• npx nx build examples-chat-angular --configuration=production-debug --skip-nx-cache
• npx nx run examples-chat-python:test --skip-nx-cache
• npx nx run examples-chat-python:smoke --skip-nx-cache
• npx nx e2e examples-chat-angular --skip-nx-cache (41 passed, 1 skipped)
• git diff --check and staged git diff --cached --check

Notes

• npm run generate-agent-context and npm run generate-api-docs were regenerated. API docs emitted the existing telemetry browser tsconfig warning.
• npm run generate-narrative-docs could not run locally because Anthropic credentials are not configured in this environment.
• npm view @threadplane/chat currently 404s as expected before the first manual publish. @ngaf/chat is still published at 0.0.46.
