feat: CLI refactoring + workspace-aware cloud project listing

Refactor CLI commands to use typed ProjectClient instead of raw HTTP calls,
and add workspace metadata to cloud project listings so users can distinguish
personal vs organization projects.

Key changes:
- 🔧 CLI commands now use ProjectClient typed API clients instead of
  call_get/call_post with manual URL construction
- 🏢 Cloud project listings include workspace_name, workspace_type, and
  workspace_tenant_id for each cloud-sourced project
- Pass config.default_workspace when fetching cloud projects via
  _fetch_cloud_projects() and CLI list_projects
- Add --workspace flag to `bm project list` for explicit workspace override
- Add "Workspace" column to CLI project list table
- Add `bm tool list-projects` and `bm tool list-workspaces` JSON commands
- Comprehensive tests for workspace passthrough, merge behavior, and CLI routing
