feat: new-app author remap (CLI scaffold → App-Refs kit)

[enricopiovesan]

Summary

• Adds the create-new-app persona path: remap traverse-cli app new manifest.json into manifests/<id>/app.manifest.json, optionally seed the traverse-starter kit bar, rewrite Web host identity/bundle path.
• Empty CLI output stays empty (no invented workflows or state machine). First slice reuses traverse-starter.pipeline / registry_ref — UI still does not compute title/tags/status.
• CI runs bash scripts/ci/new_app_author_check.sh on every PR. Live app new still needs TRAVERSE_REPO locally.

Governing Spec

• Constitution: UI rendering layer; embedded production path (no required traverse-cli serve).
• Traverse spec 044 (app new empty scaffold; examples already use app.manifest.json).
• Specs 001/002 for the copied Web host event path.
• Won’t Fix in this repo: renaming Traverse app new output.

Project Item

• Ticket ID: new-app-author-e2e
• Item: PVTI_lADOEbiBt84BbzAzzg4DGRk — New-app author E2E (traverse-cli + App-Refs recipe)
• Status: In Progress (Cursor)

Definition of Done

• Persona runbook for creating a new app id (docs/new-app-author.md)
• One OS proven (Web): host constant rewrite + Embedded README twin in new_app_author_check.sh
• app-manifest-schema.md gaps closed (remap table + Won’t Fix CLI filename)
• Validation commands listed (new_app_author_check.sh; optional app validate with TRAVERSE_REPO)
• No traverse-cli serve as the production path
• Production baseline N/A for a new checked-in product shell (no fifth primary app in tree)

Validation

• bash scripts/ci/new_app_author_check.sh — PASS
• bash scripts/ci/repository_checks.sh — PASS
• Negative: remap helper does not encode traverse-cli serve / :8787 as production

Checklist

Traceability

• Project 2 ticket claimed (Cursor, In Progress); Ticket ID cited above
• README More docs + kit-runner / playbook / schema links
• Blocked MCP tickets unchanged

Production baseline (platform / runtime-client PRs)

• N/A — recipe + CI remap; no new platform client checked in. First product shell still copies traverse-starter Web (embedded).

Architecture

• No business logic added to UI layer
• No private Traverse internals imported
• Empty app new is not treated as a runnable product app
