feat: add ASSET_SIDEBAR location constants [Ext-6786]

[Tyler (tylerwashington888)]

Why UI Extensions SDK Needs These Changes

1. Location Detection for Apps
   Apps need to know where they're running. The UI Extensions SDK provides this through sdk.location.is():
   Without the location constant, this check would fail because the SDK doesn't recognize 'asset-sidebar' as a valid location.

// In an app, developers write:
if (sdk.location.is('asset-sidebar')) {
  // Render asset-sidebar specific UI
}

2. Type Safety
   The Locations interface provides TypeScript type safety:

// This ensures only valid locations can be used
sdk.location.is('asset-sidebar') // ✅ TypeScript knows this is valid
sdk.location.is('invalid-location') // ❌ TypeScript error

3. SDK API Consistency
   The UI Extensions SDK is the central source of truth for all location constants. Other parts of the system (like the widget renderer) import and use these constants:

// In experience-packages, they import from ui-extensions-sdk:
import { locations } from '@contentful/ui-extensions-sdk'
// Then use: locations.LOCATION_ASSET_SIDEBAR

4. App Framework Integration
   When an app is loaded in the asset-sidebar location, the UI Extensions SDK needs to:

• Recognize the location type
• Provide the appropriate APIs for that location
• Handle location-specific behavior

Summary by CodeRabbit

• New Features
  • Added support for an Asset Sidebar location in the interface, allowing compatible apps or widgets to appear alongside asset details.
  • Users may now access contextual tools directly from the asset sidebar for a smoother workflow and quicker actions without leaving the asset view.

Walkthrough

Adds a new location key, LOCATION_ASSET_SIDEBAR ('asset-sidebar'), to the Locations map and its corresponding Typescript interface, extending recognized location identifiers without altering existing logic.

Changes

Cohort / File(s)	Summary
Locations mapping update lib/locations.ts	Added LOCATION_ASSET_SIDEBAR mapped to 'asset-sidebar' in the exported Locations object.
Type interface extension lib/types/api.types.ts	Added LOCATION_ASSET_SIDEBAR: 'asset-sidebar' to the Locations interface.

Poem

A rabbit taps keys with a gentle flair,
“asset-sidebar” now hops into our lair.
New nook, new burrow in the code’s green glade,
Types and maps agree—foundations laid.
Thump-thump! I file this change with care.

389-389: Consider asset-scoped SDK typing (follow-up).

If apps will run in Asset Sidebar soon, consider adding asset-scoped IDs (e.g., asset) and a context-aware SDK (new AssetSidebarAppSDK or widening SidebarAppSDK) so types match runtime.

389-389: Type entry added — verified.

ConnectMessage.location is typed as Location[keyof Location] (lib/types/api.types.ts) so 'asset-sidebar' is included.
'asset-sidebar' only appears in lib/locations.ts and lib/types/api.types.ts — no other consumers found.

New location key added — looks good.

Addition aligns with existing naming and mapping conventions.

Run to confirm type availability and barrel re-exports resolve correctly, and that Location[keyof Location] includes 'asset-sidebar':

Fix ConnectMessage type: Location is undefined — use Locations

Locations interface (lib/types/api.types.ts:385) and lib/locations.ts include 'asset-sidebar', but ConnectMessage uses location: Location[keyof Location] (lib/types/api.types.ts:399); there is no Location type in the repo so this resolves to the global DOM Location and does not include 'asset-sidebar'. Action: change to location: Locations[keyof Locations] or add export type Location = Locations in the types so the indexed type includes the new literal.

🤖 Prompt for AI Agents

In lib/locations.ts around line 7, the export LOCATION_ASSET_SIDEBAR adds
'asset-sidebar' to the Locations map but ConnectMessage in
lib/types/api.types.ts uses a non-existent Location type causing TypeScript to
resolve to the global DOM Location and miss this literal; fix by updating the
ConnectMessage type to reference the correct indexed type (location:
Locations[keyof Locations]) or add an export alias type (export type Location =
Locations) in the types file so the indexed type includes 'asset-sidebar' and
other literals.
