test: add CLI command test pattern + 142 generated tests
Big coverage push: 7.9% -> 18.5% total by adding generated tests for 19 CLI command modules (areas, banners, branch_policies, builds, connections, extensions, folders, imports, iterations, logout, packages, pull_requests, releases, repos, security, teams, users, whoami, wikis). Each test file uses the established pattern: - Mocks Azure DevOps HTTP API via TestServer (Bandit) - Captures CliMate.halt_* via CliMate.CLI.ProcessShell - Verifies the request was made correctly - Covers the success (200) and error (500) paths Tests are generated by scripts/gen_cli.exs which maps each function to its expected HTTP method, path template, and args. Manual tweaks may be needed for subcommands with complex arguments. Updated test/support/cli_test_helper.ex to use ProcessShell properly and provide consistent expect_* helpers. 138/142 tests pass. 4 fail due to edge cases (delete-with-confirm prompts, etc.) which require stdin mocking. Per-module coverage now: Projects: 62.1% (was 0%) WorkItems: 55.6% Pipelines: 34.1% AgentPools: 24.1% Helpers: 77.7% (was 0%)
