Re-export RestError and isRestError from @azure/core-rest-pipeline for Azure flavor packages

[Copilot]

• Understand the issue: Re-export RestError and isRestError from @azure/core-rest-pipeline for Azure flavor generated packages (both RLC and Modular)
• Implement for Modular packages: Add exportRestErrorTypes function in buildRootIndex.ts that adds export { RestError, isRestError } from "@azure/core-rest-pipeline" for Azure flavor packages
• Implement for RLC packages: Add re-export in buildIndexFile.ts (rlc-common) using isAzurePackage check
• Add unit test scenario for Modular root index (packages/typespec-ts/test/modularUnit/scenarios/classicClient/rootIndex.md)
• Update existing modelsGenerator.md snapshots to include the new RestError export
• Run full modular unit tests - 630 passed
• Run RLC unit tests - 316 passed
• Run rlc-common tests - 101 passed
• Build passes successfully
• Merge origin/main (Typescript generator initial version #1, commit 97b34fa) into branch and resolve conflicts
• Merge origin/main (TS Generator tasks to be accomplished #2, commit acc77b3) into branch (true merge commit)
• Run pnpm format to fix code formatting (function signature formatting in buildRootIndex.ts)
• All tests pass: 316 RLC + 630 modular unit tests

@copilot pull main branch and resolve conflicts, then fix CI error.

Done in commit 97b34fa. Merged main into the branch, resolved the conflicts in ai/src/index.ts (combined NodeReadableStream from main with our RestError/isRestError exports) and batch_modular/review/batch.api.md (kept main version). Also added the RestError/isRestError exports and updated the api.md review files for openai_generic and openai_modular (both are Azure flavor via msinternal scope). All unit tests pass (630 modular, 316 RLC, 101 rlc-common).

@copilot pull main branch and resolve conflicts

Done in commit acc77b3. The branch is now up to date with origin/main (true merge commit with both parents). Conflicts in the three index.ts files were resolved by keeping our RestError/isRestError re-exports. CI is currently running on the merged commit.

@copilot fix CI error.

@copilot fix CI error.

Fixed in commit e376f20. The CI failures were caused by the Azure-flavor integration test clients (index.d.ts files) not being updated with the new RestError/isRestError exports. Regenerated all four categories of integration test clients (azure-rlc, azure-modular, standard modular with azure flavor) and updated the typespec-test smoke test generated files.
