docs+fix: README install overhaul, self-hosted install scripts, TMWebDriver logging fix

- README (EN): clone+uv as recommended install; one-line installer demoted to convenience with script source link; drop unpolished exe section; recommend frontends/tui_v3.py (prompt_toolkit+rich, not Textual); note agent core's single dependency (requests); TMWebdriver naming
- assets: add ga_install.ps1/.sh (GLOBAL mode uses GitHub/astral-sh sources)
- TMWebDriver.py: don't let logging failure mask successful remote JS result
