feat(console): isolate production browser acceptance

[XnLemon]

Summary

• Import the reviewed production Console into apps/console.
• Run real Playwright production acceptance against a fresh Compose Gateway.
• Keep / production flow separate from isolated #/demo routes.
• Verify Gateway-only JSON/SSE/trace behavior, reverse lineage, lifecycle failures, and secret boundaries.

Scope

• Resolves NeKiro-Console#3 and contributes to NeKiro#59.
• Stacked on codex/027-slice-c-reverse-lineage (PR test(platform): isolate reverse cross-runtime acceptance #63).
• No backend contract, seed API, retry, fallback, alternate endpoint, or direct Agent/Router access.

Verification

• pnpm install --frozen-lockfile
• pnpm typecheck
• pnpm test (36/36)
• pnpm build
• git diff --check
• Root CI browser and backend acceptance passed in run 30319275997 on the equivalent integrated checkout.

Slice D final delivery evidence (commit 3dad843):

• PR feat(console): isolate production browser acceptance #64 remains stacked on Slice C PR test(platform): isolate reverse cross-runtime acceptance #63 and is Console/CI/Spec-only; no Router, Control Plane, contract, database, direct Agent, or alternate endpoint changes.
• CI run 30329624757: all 8 checks passed, including frontend, go-quality, backend-acceptance, workspace-integration, runtime-samples-quality, compose-config, console-browser-acceptance, and Codecov.
• Local verification: pnpm test 41/41, pnpm typecheck, pnpm build, and git diff --check.
• The prior browser failure in run 30328793812 was diagnosed as the read-only Header status layer intercepting the Create Workspace control at the CI viewport. Commit 3dad843 adds pointer-events-none to that status layer; the fresh browser acceptance passed.
• Final independent review of 253c187..3dad843: 0 High / 0 Medium / 0 Low.
• Fallback delta: removed 1 implicit Agent-selection fallback, retained 0, added 0, net -1. Added fallback evidence: none.

The historical T005 ordering deviation remains recorded in Spec 027 and is not being rewritten as satisfied.

Phase 9 convergence delivered in commit 3246e7d. Fixed exact Number.MAX_SAFE_INTEGER uint64 SemVer caret/wildcard successor handling and cleared stale Binding confirmation state after failed authoritative reads. Verification: pnpm install --frozen-lockfile, pnpm test (42/42), pnpm typecheck, pnpm build, git diff --check. Fresh independent reviewer Carver: PASS, 0 High / 0 Medium / 0 Low. Local Docker is unavailable, so fresh-Compose browser acceptance remains the CI gate.
