fix(cli): scaffold emits aspire start not aspire run (alpha.11 Slice G)

[rickylabs]

Summary

Fixes the alpha.11 fix-train gap where scaffolded project output still instructed users to run the invalid aspire run command even though the TypeScript AppHost template already points at aspire start. Refs #141 #153.

Scope

• Archetype / area: CLI tooling / scaffold output
• Slice: alpha.11 Slice G
• Branch: fix/scaffold-aspire-start-alpha11-g

Changes

• Updated generated project README TypeScript AppHost quick start, project structure note, command table, and database provisioning prose from aspire run to aspire start.
• Updated init next-steps for non-legacy TypeScript AppHost scaffolds to emit aspire start # start TypeScript AppHost.
• Updated app template and Aspire config source comments, then regenerated packages/cli/src/kernel/assets/embedded.generated.ts via deno task gen:assets-barrel.
• Updated focused assertions so non-legacy README output requires aspire start and rejects aspire run; legacy C# AppHost remains dotnet run.

Validation

• deno run --allow-read --allow-run .llm/tools/run-deno-check.ts --root packages/cli --ext ts,tsx — PASS, 527 files selected, 5 batches, 0 failed batches.
• deno test --allow-all packages/cli/src/kernel/templates/workspace/generators_test.ts packages/cli/src/kernel/application/scaffold/orchestrate-init_test.ts — PASS, 18 passed / 0 failed.
• rg -n "aspire run" packages/cli/src --glob '!**/*_test.ts' --glob '!**/*.test.ts' — PASS, no scaffold source/template occurrences.
• git diff --check — PASS.
• deno lint --no-config <touched .ts files> — PASS, 6 files checked.
• deno fmt --check --no-config --single-quote --line-width 100 --indent-width 2 packages/cli/src/kernel/templates/workspace/generate-readme.ts — PASS.

Requested wrappers with the exact root commands were also run:

• deno run --allow-read --allow-run .llm/tools/run-deno-lint.ts --root packages/cli --ext ts,tsx — exit 1 with JSON summary showing 527 files selected and 0 findings. Raw deno lint packages/cli/... reports No target files found because root deno.json explicitly excludes packages/cli/ under lint.exclude.
• deno run --allow-read --allow-run .llm/tools/run-deno-fmt.ts --root packages/cli --ext ts,tsx — exit 1 with JSON summary showing 527 files selected, 0 findings, and failed batches. Raw deno fmt --check packages/cli/... reports No target files found because root deno.json explicitly excludes packages/cli/ under fmt.exclude.

Harness

• Phase: implementation slice complete; separate OpenHands IMPL-EVAL still required.
• Commit: 9b82271e

Drift / Debt

• No code drift or architecture debt introduced.
• Gate caveat: root lint/fmt wrappers are currently non-actionable for packages/cli because the root Deno config excludes that package from lint/fmt target discovery.

Slice G — scaffold emits aspire start (alpha.11 fix-train)

Blocker: Run-1 eye-test F-12 — scaffolded workspaces instructed users to run aspire run, which is not a valid Aspire CLI command (the CLI verb is aspire start), orphaning the AppHost on Windows.

Commit: 9b82271e — 7 files, +14/-11

File	Change
init-orchestrator.ts	next-step aspire run → aspire start (TS AppHost)
generate-readme.ts	4 sites: start cmd, tree comment, command table, provision prose (legacy C# keeps dotnet run)
main.ts.template	startup-banner comment
generate-aspire-config.ts	doc comment
embedded.generated.ts	regenerated from the template (not hand-edited)
orchestrate-init_test.ts / generators_test.ts	expectations flipped + 3 new negative assertions (!md.includes('aspire run'))

Verification

• Targeted tests: 18 passed / 0 failed (generators + orchestrate-init).
• CI on this PR: check-test ✅, quality ✅, scaffold-static ✅, scaffold-runtime (aspire + docker + postgres) ✅, deps-report ✅.
• Residual aspire run in packages/cli/src: 3 — all are the new negative test assertions (intentional; they assert the string is absent from generated READMEs).

Legacy C# AppHost path intentionally retains dotnet run. Zero logic changes — string/template + test deltas only.
