Add cloudos project members command for /api/v1/projects/{id}/members

[Copilot]

Overview

Adds CLI support for the newly introduced GET /api/v1/projects/{id}/members endpoint so project member retrieval is available from cloudos project.
Also updates release metadata to keep endpoint manifest, versioning, and changelog aligned with the API contract change.

Changes

• CLI surface
  • Adds cloudos project members with --project-id, --apikey, --cloudos-url, SSL/profile options.
• API client
  • Adds Cloudos.get_project_members(project_id, verify=True) calling /api/v1/projects/{id}/members with existing error semantics (BadRequestException on non-2xx).
• Contract/release metadata
  • Bumps patch version to 2.91.1.
  • Adds top changelog entry for the new command.
  • Adds/updates supported-endpoints.json with:
    • projects-create (existing)
    • projects-members-list (new)

# new client method shape
def get_project_members(self, project_id, verify=True):
    r = retry_requests_get(
        f"{self.cloudos_url}/api/v1/projects/{project_id}/members",
        headers={"Content-type": "application/json", "apikey": self.apikey},
        verify=verify,
    )
    if r.status_code >= 400:
        raise BadRequestException(r)
    return json.loads(r.content)

Acceptance Criteria

Please add here as many scenarios as in the Story

Normally this acceptance criteria is tested in ADAPT workspace in PROD

Scenario 1 - proof this scenario passes

cloudos project members --help exposes the new command and required --project-id argument under project.

Scenario 2 - proof this scenario passes

Valid project ID invokes GET /api/v1/projects/{id}/members and returns member payload to stdout (JSON).

Scenario X - proof this scenario passes

Non-2xx responses from /api/v1/projects/{id}/members propagate through existing error handling (BadRequestException path).

DEV

This Environment is interchangable with PROD if the acceptance criteria can only be tested in DEV for example. If that is the case please name this section PROD (or any new environment)

Proof this feature/patch works in this environment

cloudos project members command is registered and wired to the new Cloudos client method in DEV CLI runtime.

AZURE

Proof this feature/patch works in this environment

Endpoint/CLI contract update is runtime-agnostic; no Azure-specific behavior introduced.

Interactive Analysis

Proof this feature/patch works in this environment

No Interactive Analysis behavior changes; command addition is scoped to project member retrieval.
