Extracted common quit/esc handling into `common_keybindings`. Introduced
`Group::CtrlMovement` for Ctrl‑arrow keys and updated keybinding
definitions.
Removed duplicated quit logic in main_menu and skirmish modules. Bumped
clap to 4.6.0 and updated Cargo.lock. Added range‑checked parsers for
map
size, resources, supply limit, XP modifier and skill points in the CLI.
Replace the `default_window` string field with a `View` enum throughout
the
application. Introduce a new keybinding module providing `Action`,
`KeyBinding` structs and helper functions, and integrate a keybindings
widget
into the main menu. Update the CLI to accept a `View` value enum and
adjust
imports and event handling accordingly. Add a release profile in
`Cargo.toml` with LTO, single codegen unit, higher optimisation level
and
binary stripping for smaller, faster builds.
