[Deploy-S7] Aspire Docker/Compose lane via TS AppHost

[rickylabs]

Scope

Aspire container lane via the TypeScript AppHost — beta slice: Docker + Compose (decision D2 co-marquee cloud-agnostic proof). Generate apphost.mts using addContainer('denoland/deno:2') / addDockerfile + publishAsDockerComposeService; route netscript deploy to aspire publish/aspire deploy; map NetScript config to Parameters__*. Not blocked on ada2a5/#320 (AddDenoApp is optional DX, folded in later). k8s + Azure publish shapes are the stable slice (S10).

Target / adapter

Docker / Docker Compose (self-host) via Aspire TS AppHost.

Acceptance criteria

• apphost.mts generated with a Deno container/dockerfile resource + publishAsDockerComposeService.
• netscript deploy docker|compose <verb> wraps aspire publish/aspire deploy; emitted compose file + image build verified.
• NetScript deploy config mapped to Parameters__* env vars.
• denoland/deno:2 base (not 2.5).
• E2E: compose artifact emits and docker compose up boots the app (or CI-safe equivalent).

Dependencies

S1 (contract). Independent of bare-metal + Deno Deploy lanes (parallel). Phase 3a.
