Changes default precision from 1/32" to 1/16" for cleaner measurements and
simplifies output by omitting unnecessary fraction components.
- Change default precision from 32 to 16
- Return whole numbers without "-0/N" suffix when fraction rounds to zero
- Update documentation to reflect new default precision
This makes measurements more readable (e.g., "12" instead of "12-0/16") while
maintaining sufficient precision for typical woodworking applications.

Improves the exported text file format with better organization, visual
hierarchy, and comprehensive summary information.
- Add header with creation timestamp and overall statistics
- Redesign bar sections with clearer labels and formatting
- Replace verbose item format with tabular layout (QTY/Length/Tag)
- Add final summary section with totals and best/worst utilization
- Use Unicode box-drawing characters for visual separation
- Fix namespace references (SawCut.FormatHelper → FormatHelper)
- Add null safety with DefaultIfEmpty for empty bin collections
- Make _bins field readonly for immutability
The new format is more professional and easier to scan visually, making it
simpler for operators to execute the cut list.

Implements grouping of identical bins (same items in same order) to reduce
visual clutter in the results grid. Instead of showing 10 identical bins as
separate rows, they now appear as a single row with a count.
- Add BinComparer for deep equality comparison of bins
- Add BinGroup to represent grouped bins with count
- Update ResultsForm to display grouped bins in grid
- Add Count column to show how many of each bin pattern
- Maintain original bins list for file export
This improves readability when the optimizer generates multiple identical
cutting patterns.

Introduce Model-View-Presenter pattern to eliminate business
logic from MainForm and enable proper separation of concerns.
New files:
- IMainView: Interface defining view contract
- MainFormPresenter: Contains all business logic orchestration
MainForm changes:
- Implements IMainView interface
- Delegates all business logic to presenter
- Focused purely on UI rendering and user input
- MessageBox calls now isolated to view implementation
Presenter responsibilities:
- Document operations (open, save, new)
- Validation orchestration
- Running packing algorithm
- Coordinating between services and view
- State management
Benefits:
- MainForm reduced from 380+ lines to clean view implementation
- Presenter can be unit tested without UI
- Business logic is reusable across different UI frameworks
- Clear separation: View = UI, Presenter = logic, Services = domain
- All SOLID principles now satisfied

Refactor DocumentService and CutListService to return Result<T>
instead of throwing exceptions or using out parameters. This
removes all MessageBox calls from business logic.
DocumentService changes:
- Load() returns Result<Document> instead of Document
- Save() returns Result instead of void
- Validate() returns Result instead of bool with out parameter
- All exceptions caught and converted to Result.Failure
CutListService changes:
- Pack() returns Result<SawCut.Nesting.Result>
- Exceptions caught and converted to Result.Failure
Benefits:
- Services are now UI-agnostic (no MessageBox)
- Can be unit tested without UI dependencies
- Can be reused in console apps, web apps, etc.
- Errors are values, not exceptions
- Clear, type-safe error handling contract

Replace hard-coded engine instantiation with factory pattern
to enable dependency injection and improve testability.
Changes:
- IEngineFactory: Interface for creating engines
- EngineFactory: Default implementation using AdvancedFitEngine
- MultiBinEngine: Now accepts IEngineFactory via constructor
This eliminates the hard-coded dependency on AdvancedFitEngine
and allows for easy swapping of engine implementations through
configuration or dependency injection.
Benefits:
- Dependency inversion principle satisfied
- Engines can be mocked in tests
- Engine selection can be configured externally
- Single responsibility for engine creation

Implement Result<T> and Result classes to provide type-safe,
functional error handling throughout the application. This
eliminates the need for exceptions as control flow and provides
a consistent way to communicate success/failure.
Features:
- Result<T> for operations that return values
- Result for operations without return values
- Map() method for functional composition
- IsSuccess/IsFailure properties for easy checking
This pattern enables cleaner service contracts and eliminates
the need for out parameters and exception handling boilerplate.

Create CutListService and DocumentService to separate business
logic from UI concerns, following the service layer pattern.
Changes:
- CutListService: Handles bin packing algorithm orchestration
and data transformation from UI models to domain models
- DocumentService: Handles document persistence and validation
- Document: Removed Save/Load/Validate methods (now pure POCO)
- MainForm: Refactored to delegate to service classes instead
of containing business logic directly
Benefits:
- Improved separation of concerns
- Business logic can now be unit tested independently
- Removed MessageBox dependencies from business logic layer
- MainForm is now focused on UI concerns only

Replace public mutable collection fields/properties with private
backing fields and expose them as IReadOnlyList. Add proper methods
for mutation (AddItem, AddItems, RemoveItem, SortItems).
Changes:
- Bin.Items: Now private with AddItem/AddItems/RemoveItem/SortItems
- Result.ItemsNotUsed: Now readonly with Add methods
- Result.Bins: Now readonly with Add methods
- Updated all engine classes to use new encapsulated APIs
This improves encapsulation and prevents external code from
bypassing business logic by directly manipulating collections.
