Refactor App, GameStates, SkirmishState and BoardState to carry a
generic
lifetime `'a`. Introduce a new `MarkedCells` type that holds marking
state
and selected unit, replacing the previous `marking_cells` flag and raw
deque. Update related methods, keybindings, view implementations and
module exports to use the new structures.
Move the GameMode and Players enums from the top‑level states module
into the
skirmish_states submodule, add an Unclaimed variant to Players, and
update all
imports, trait implementations, and related logic accordingly. Adjust
the
durability percentage calculation to use u32 for safety.
Introduce Structure and Unit traits with enum wrappers.
Replace old zoom helper with ZoomLevel methods.
Update imports, BoardState, CellWidget, and CLI to use new locations.
Introduce a MoveFocusedCell enum and a BoardState.change_focused_cell
method to
centralize focus movement logic. Update skirmish keybindings to use this
new
method and simplify board rendering by directly using stored CellWidget
state.
Make CellWidget setters chainable and expose the new enum in the module
re‑exports. Remove duplicated max_offset logic and old move_* methods.
App now stores CLI arguments and an optional GameStates, initializing
the
states lazily on the first window resize. Skirmish board logic is moved
to
a new BoardState module with dedicated helpers (cells_area_helper and
updated cell size handling). Views and keybindings are updated to use
the
optional state accessors.
Extract Offset and FocusedCell structs from skirmish.rs into a new
skirmish_states module. Re-export the structs from the top-level states
module and adjust imports in skirmish.rs.
