feat: bootstrap scripts auto-launch the installer

get-cameleer.sh and get-cameleer.ps1 now download the installer files
and exec install.sh / install.ps1 immediately instead of just printing
a "run this next" hint. Extra arguments are forwarded to the installer.

PowerShell bootstrap fetches install.ps1 (not install.sh) so Windows
users no longer need bash. README updated to use the bash -c "$(curl ...)"
form so install.sh's interactive prompts inherit the user's TTY.
