Install lazygit as an opt-in tool

[primetimetank21]

Install lazygit -- terminal UI for git commands.

Scope

• New tool installer at scripts/linux/tools/lazygit.sh (GitHub release tarball is most reliable; Ubuntu PPA lags badly)
• Windows counterpart at scripts/windows/tools/lazygit.ps1 (winget preferred, scoop fallback)
• Wire into the install pipeline behind the new flag framework (filed separately)

No config required

lazygit works out-of-the-box. No global git config changes needed.

Out of scope

• Custom keybindings / theme (users can configure ~/.config/lazygit/config.yml post-install)

Verification

• New parity test pair (bash + pwsh) for the installer
• Verify lazygit --version reports a version after install
• Verify binary is on PATH

Dependencies

• Should land after the flag framework (filed separately) so it slots in as an opt-in tool from day one.
