[release/13.2] Export more importable ATS hosting APIs

[sebastienros]

Description

Expand the importable ATS/polyglot export surface across Aspire.Hosting, Aspire.Hosting.Azure, and Aspire.Hosting.Foundry.

• convert compatible [AspireExportIgnore] APIs into importable ATS exports, including union- and DTO-based shims for overloads and flags enums
• unify split ATS method names where the guest-language surface can share one logical API, including connection-property and Azure existing-resource helpers
• update the TypeScript validation apphosts and checked-in generated SDKs to compile against the new exports
• switch the checked-in polyglot validation apphosts to aspire.config.json and remove the legacy .aspire/settings.json files

Pull request overview

Expands the importable ATS/polyglot export surface across Aspire.Hosting, Aspire.Hosting.Azure, and Aspire.Hosting.Foundry, and updates the TypeScript polyglot validation apphosts + checked-in generated SDK outputs to compile against the new exports (including moving validation apphosts to aspire.config.json).

Changes:

• Adds union/DTO-based ATS-safe dispatcher exports (e.g., addContainer, withBuildArg, withConnectionProperty, withReferenceEnvironment) and new ATS DTOs.
• Exports additional Azure/Foundry resource APIs to polyglot (including “existing resource” helpers and more resource/property exports).
• Regenerates TypeScript validation apphosts’ .modules output and updates snapshots to reflect the new capability surface.

Re review 4007242739: declining this as an actionable comment because it is the review summary rather than a specific issue to address. I evaluated the concrete unresolved threads below and applied the warranted fixes there.

[sebastienros]

Reviewed the five comments called out in automation: 4007242739 is the Copilot review summary (informational only, so no code change); 2986149613/2988637945 were accepted and I pushed 1d18d71 to make the TypeScript DTO usage clearer in the validation apphost; 2988731875 and 2988731938 were already accepted earlier on the branch, and I verified both corresponding threads are already resolved with the fixes present in the current code.

[github-actions]

Re-running the failed jobs in the CI workflow for this pull request because 1 job was identified as retry-safe transient failures in the CI run attempt.
GitHub was asked to rerun all failed jobs for that attempt, and the rerun is being tracked in the rerun attempt.
The job links below point to the failed attempt jobs that matched the retry-safe transient failure rules.

• Tests / Hosting-1 / Hosting-1 (windows-latest) - Job-level runner or infrastructure failure matched the transient allowlist.

Fixed merge

[sebastienros]

I think this PR got corrupted.

You're the branch briefly picked up an accidental merge from main, which made the PR look corrupted. I reset it back onto release/13.2, cherry-picked only the intended PR commits, and force-pushed the corrected history; the current branch ancestry is back to release/13.2.right

Breaking changes:

Previous name	New name	Notes
runAsExistingFromParameters(name, resourceGroup)	runAsExisting(name, { resourceGroup })	Name change plus positional → options object.
publishAsExistingFromParameters(name, resourceGroup)	publishAsExisting(name, { resourceGroup })	Name change plus positional → options object.
withConnectionPropertyValue(name, value)	withConnectionProperty(name, value)	Unified API for string/reference values.
withParameterBuildArg(name, parameter)	withBuildArg(name, parameter)	Renamed to the unified withBuildArg surface.

One nuance: withConnectionPropertyValue is now restored as a compatibility alias in the generated SDKs, so it’s not a runtime SDK break anymore, even though the updated apphost.ts samples were migrated to withConnectionProperty

Are these the only ones? If so, I think it's fine to take in servicing as long as we document these in the release notes. If more extensive, I would probably lean towards pushing to the next minor release.

@sebastienros can we fix this as well?
