Remove ASPIREATS001

[aaronpowell]

The AspireExportAttribute is still marked as experimental which means we need to ignore ASPIREATS001 still, but I don't think this should be needed in 13.4

Area: area-app-model
Kind: feature-request (graduate experimental API)
Repro: n/a — request to remove the ASPIREATS001 experimental diagnostic for AspireExportAttribute
Affected version(s): 13.4 (currently snapped)
Severity: S4 — API polish; no behavioral break, only the experimental marker

Urgency: 🟡 vNext — recommend milestone 13.5
Reason: 13.4 is snapped and ships Monday. Graduating an experimental attribute in a snapped release is a release-team call, not a bot call. The author (Aaron Powell, microsoft/*) explicitly suggests it should land in 13.4 — flagging for human confirmation rather than auto-routing into the snapped milestone.

• JamesNK is the dominant area-app-model author over the last 90d (Use KnownConfigNames for resource service endpoint URL with legacy fallback #17385, Use OrdinalIgnoreCase for EnvironmentVariableName comparer #17194, CLI: Print app host CLI log path when connected to a running app host #17168, Improve version log messages in CLI, AppHost and dashboard #17163, Use ASPIRE_APPHOST_LOGLEVEL instead of cascading Logging__LogLevel__Default #17071, Use arguments for built-in resource commands #17021, Handle non-interactive interaction service availability for resource commands #16973, Fix OTLP endpoint resolution in isolated mode #16367, Downgrade AuxiliaryBackchannelRpcTarget log messages from Info to Debug #16365, Use display name without DCP suffix in resource command error messages #16148, Refactor name validation to NameValidationPolicyAnnotation with configurable rules #15728, Fix GuestAppHostProject launchSettings.json parsing with JSON comments #15302, Downgrade IOException log for client disconnect on aux backchannel #15092, Rename built-in resource commands: resource-start/stop/restart -> start/stop/restart #14930)
• AspireExportAttribute and the ASPIREATS001 diagnostic live in the app-model surface, which JamesNK has been actively shaping for 13.4

Confidence: low (milestone) / high (area + owner)
Needs human?: yes — release team must decide whether to graduate AspireExportAttribute (drop ASPIREATS001) in the snapped 13.4 or defer to 13.5
