Implement boundary selection functionality for select command

[devill]

Problem

The select command has boundary selection functionality that is currently not implemented, causing several tests to be skipped.

Current Status

Four boundary selection tests are currently skipped:

• tests/fixtures/commands/select/boundary/arrow-function.input.ts
• tests/fixtures/commands/select/boundary/class-method.input.ts
• tests/fixtures/commands/select/boundary/inline-function.input.ts
• tests/fixtures/commands/select/boundary/standalone-function.input.ts

What is Boundary Selection?

Boundary selection allows users to select code elements by their boundaries (e.g., entire function bodies, class methods, etc.) rather than precise character ranges.

Example Use Cases

# Select entire function including signature and body
refakts select myfile.ts --boundary function

# Select complete class method
refakts select myfile.ts --boundary method

# Select arrow function expression
refakts select myfile.ts --boundary arrow-function

Implementation Needed

1. Boundary Detection Logic

• Function boundaries: Include signature, parameters, and complete body
• Method boundaries: Include visibility modifiers, signature, and body
• Arrow function boundaries: Include parameters and expression/body
• Class boundaries: Include entire class definition

2. Selection Strategy

• Extend existing selection strategies in src/core/services/selection/
• Add boundary-specific pattern matching
• Integrate with existing SelectCommand architecture

3. Output Format

• Use existing SelectOutputHandler for consistent formatting
• Return complete boundary ranges rather than partial selections

Related Skipped Tests

All tests use @skip annotation and need to be enabled after implementation:

1. arrow-function.input.ts - Select arrow function boundaries
2. class-method.input.ts - Select class method boundaries
3. inline-function.input.ts - Select inline function boundaries
4. standalone-function.input.ts - Select standalone function boundaries

Acceptance Criteria

• Implement boundary selection strategy for functions
• Implement boundary selection strategy for class methods
• Implement boundary selection strategy for arrow functions
• Add boundary selection options to select command
• Update all 4 skipped boundary tests to pass:
  • arrow-function.input.ts
  • class-method.input.ts
  • inline-function.input.ts
  • standalone-function.input.ts
• Remove @skip annotations from boundary tests
• Update command help text to document boundary selection options

Priority

Medium - Enhances select command functionality but doesn't block existing features.
