Task: Integrate project setup UX

Identity

Integrate source task 20260906-project-setup-ux-90fe6cf2 at 8042d2be265e40288e628fcdc755e9f29151306b onto main at 83ad10d95e607c10973fed543cc5fa09afdcb9f7.
Preserve the Token Point V2 sidebar behavior already on main while adopting the shared Coding Project conversation-readiness gate and project-setup onboarding flow.
Promote the source task's accepted readiness invariant into .project-docs/30-worklog/current-state.md.
Verify the exact merged tree and leave the three pre-existing adopted task records unchanged and outside the integration commit.

Use a normal non-history-rewriting merge; do not squash, rebase, force-push, package, deploy, or push remotely.
Treat the source task record as read-only source evidence until it is intentionally adopted as part of the merge commit.
Preserve the accepted .makelore/project.json authority, Pi runtime structure, Main-owned boundaries, and single light visual system.
Do not modify or commit the adopted records 20260901-package-122-c5e8.md, 20260901-package-123-d7f3.md, or 20260902-client-hang-diagnosis-a47c9e2b.md.
Re-run focused onboarding/readiness tests, typecheck, lint, Renderer build, the relevant Electron E2E, and the full unit suite because the source and destination both modify Sidebar.tsx.

Merged codex/20260906-project-setup-ux-90fe6cf2-project-setup-ux into the current main with --no-commit --no-ff; Git reconciled the shared src/components/layout/Sidebar.tsx change without conflicts.
Preserved the Token Point V2 version of Sidebar and added only the shared Coding Project conversation-readiness import and navigation predicate from the source.
Integrated the shared readiness contract, required first-Agent setup card, deterministic configuration exits, and Coding chat recovery state together with their focused unit and Electron E2E coverage.
Registered the unchanged source task record as an adopted integration input and promoted its accepted readiness invariant into canonical current-state.md.
Kept the three pre-existing adopted task records unstaged and unchanged.

Focused Vitest passed 5 files / 63 tests for readiness, App and MainLayout gates, Project Configuration onboarding, and Coding chat recovery.
Full pnpm test passed 231 files / 1,936 tests with 2 skipped; the separately serialized Coding chat pressure test passed 1/1.
pnpm run typecheck passed.
pnpm run lint:check passed with 0 errors and the 5 unchanged warnings in src/pages/Home/index.tsx and src/pages/Makelore/index.tsx.
pnpm run build:vite passed for Renderer, Electron Main, preload, and utility bundles; only the repository's existing Browserslist, dynamic-import, and chunk-size advisories were reported.
Electron E2E tests/e2e/project-configuration-skills.spec.ts passed 1/1.
check_project_docs.py, task-aware check_doc_drift.py, the unchanged source-task record comparison, and git diff --check all passed before the merge commit.

None. This Integration Gate applies the accepted source promotion directly to .project-docs/30-worklog/current-state.md.
