lib/msal-browser/docs/instance-aware.md:1

• This PR removes the instance-aware documentation file but does not remove the actual implementation code. The instanceAware configuration option and instance_aware query parameter are still implemented in:

1. Configuration files:

   • lib/msal-browser/src/config/Configuration.ts (line 92, 258)
   • lib/msal-common/src/config/ClientConfiguration.ts (line 82, 92, 261)

2. Implementation code:

   • lib/msal-browser/src/interaction_client/BaseInteractionClient.ts (lines 159-177)
   • lib/msal-common/src/client/AuthorizationCodeClient.ts (line 579-581)
   • lib/msal-common/src/protocol/Authorize.ts (lines 256-265)

3. API surface:

   • lib/msal-browser/apiReview/msal-browser.api.md (line 287)
   • lib/msal-common/apiReview/msal-common.api.md (line 612)

4. Tests:

   • Multiple test files in both msal-browser and msal-common

If the intent is to deprecate this feature, you should also:

• Remove the implementation code
• Remove the configuration options
• Update the API review files
• Remove or update related tests
• Add deprecation notices if this is a phased removal
• Create a migration guide if applications are using this feature

Additionally, lib/msal-browser/docs/configuration.md line 86 still documents the instanceAware configuration option and should be removed.
