Add query parameter list serialization test for CSV format

[Copilot]

Plan: Add query parameter as list parameter test

• Explore repository structure and understand existing tests
• Add list parameter scenario in /packages/http-specs/specs/parameters/query/main.tsp
• Add corresponding mock API in /packages/http-specs/specs/parameters/query/mockapi.ts
• Validate the scenario format
• Validate the mock API
• Test the implementation and verify formatting
• Run E2E tests to verify functionality
• Verify test passes and is included in coverage
• Address PR feedback: Rename interface from List to QueryList
• Add changelog entry for the http-specs package

Implementation Summary

Successfully added a new test scenario Parameters_Query_QueryList_post for query parameters with list/array values:

Changes Made:

1. main.tsp: Added QueryList interface with a POST operation that accepts listParameter: string[] as a query parameter
2. mockapi.ts: Added mock API definition expecting the list to be serialized as CSV ("a,b,c")
3. spec-summary.md: Auto-generated documentation showing the new test
4. Changelog: Added chronus change file for the new feature

Test Details:

• Endpoint: POST /parameters/query/list
• Parameter: listParameter (type: string[])
• Expected behavior: Client should pass array ["a", "b", "c"] and it should be serialized as "a,b,c" (CSV format)
• Response: 204 No Content

Validation Results:

✅ Scenario validation: PASSED
✅ Mock API validation: PASSED
✅ Code formatting: PASSED

PR Feedback Addressed:

• Renamed interface from List to QueryList as requested
• Updated mock API scenario name to Parameters_Query_QueryList_post to match
• Added changelog entry using chronus format

This section details on the original issue you should resolve

<issue_title>Add query paramerter as list parameter test</issue_title>
<issue_description>I need a new test in "packages/http-specs/specs/parameters/query" to test what happen if the parameter is a list:

@query
listParameter: string[];

It's expected that the list is serialized as CSV. The scenario should ask for the person calling this test, to pass an array like {"a","b","c"], and the http part should expect to receive "a.b.c" for the query parameter.</issue_description>

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot you need to update the ChangeLog of the http-specs package for the CI to pass
