refactor: rename project to hy3d, full CLI overhaul

- package hunyuan3dweb/ -> hy3d/ (imports: from hy3d import ...)
- CLI: MiniMax-style verb/noun commands (quota/list/status/formats/
  download/text/image/multi-view/sketch/animate/texture/topo/cancel/
  share/auth/config), global --json/--cookies, env HY3D_COOKIES/HY3D_JSON
- exit codes: 0 ok / 1 env / 2 auth-expired / 3 cookie-missing
- generation commands support --wait polling with stderr progress
- local images auto-upload to COS in image/multi-view/sketch/animate/texture/topo
- old commands removed (no backwards compat)
- config dir kept at ~/.config/hunyuan3dweb to preserve existing cookies
- deps: requests>=2.32.3, browser extras cloakbrowser>=0.3.31/playwright>=1.40
- skill updated: bin/hy3d shim replaces driver.sh; all commands live-verified
