v0.7.3

Reworks the one-line installers so a single command provisions the full toolchain on a fresh machine, and makes both platforms default to the latest published release.

Windows one-line install — fixed

• Clone into %LOCALAPPDATA% (not the write-protected C:\Windows\System32) and set a process-scope ExecutionPolicy Bypass before running the cloned installer.
• Reject the Microsoft Store python.exe / python3.exe alias stubs; auto-install Python 3.12 (required) and Node.js LTS (best-effort) via winget; add the venv Scripts dir to PATH so aiswmm resolves after install.

Installer entrypoints — changed (both platforms)

• Default to the latest published release; AISWMM_INSTALL_REF pins a tag or main.
• The upfront OpenAI-only model prompt is gone — provider/model are chosen after install via aiswmm login / aiswmm login --anthropic.
• A CI job keeps aiswmm.com/install.* in lockstep with web/install.*.
