v0.1.2
Terminal and install-location hardening.
- install.sh: only emit 24-bit truecolor when the terminal advertises it (COLORTERM). Terminals without truecolor (macOS Terminal.app, older terminals) now get clean plain block art instead of wrong colors.
- install.sh: honor ZDOTDIR when choosing which .zshrc to update, so users who relocate their zsh config are not left with the tool silently unloaded.
- Docs: drop the stale 'uses select' claim.
Builds on 0.1.1 (Linux/dash install fix, missing-agent guard, demo GIF).
