refactor(cli): cover functions serve-main-bundler with effect lint (CLI-2592)

[7ttp]

TL;DR

brings the serve main bundler and its tests under the effect lint

whats introduced?

• serve-main-bundler.ts and its unit and integration tests join the allow list
• bundleServeMainTemplate now returns an effect, which serve.ts yields and the build scripts and offline e2e run with Effect.runPromise
• the template bundles in a detached fiber that serve.ts joins, so an interrupted startup still fills the template cache, and an esbuild failure stays a defect
• the bundler integration tests keep all eighteen cases and coordinate through Deferred and scoped abort signals instead of manual promises, with the fake Deno.errors classes as Data.Error
