refactor: introduce fluent DSL with equivalent method names for flexible terminology

* refactor: introduce fluent DSL with equivalent method names for flexible terminology

Add multiple equivalent method names to support different team conventions:
- AddControl/AddDefaultTrial for baseline implementations
- AddCondition/AddVariant/AddTrial for alternative implementations
- Trial/Define for experiment definitions

Changes include:
- New builder methods with consistent fluent API design
- Time-based activation (ActiveFrom, ActiveUntil, ActiveWhen)
- Named experiments spanning multiple service interfaces
- Trial conflict detection and validation
- Updated source generators to recognize new method names
- Comprehensive documentation explaining the fluent DSL philosophy
- Updated all docs, samples, and tests to use new terminology

* feat: split out providers into serparate packages.

* tests: added additional test coverage

* test: add unit tests for TrialConflictException and ExperimentBuilder validation

* chore: add coverage run settings for code coverage configuration

* ci: update code coverage settings for improved reporting

* test: enhance null handling and improve fallback key validation

* test: improve null handling in ExperimentBuilder and RuntimeExperimentProxy tests

* fix: remove trivial self-comparison assertion in Equals test

Replace Assert.True(db.Equals(db)) with meaningful assertions that
test actual proxy behavior - null handling and type mismatch cases.

* test: improve RuntimeExperimentProxy Equals test coverage

- Test null handling behavior
- Test type mismatch comparisons (string, int)
- Verify proxy type checking works
- Verify functional consistency across scopes
