Add compatibility aliases, PlayStation controller presets, and FTC sample starters

[elluveride]

Motivation

• Reduce friction for teams migrating from other command DSLs by adding alias methods and broader controller vocabularies.
• Provide copy-ready sample hardware and autonomous templates to accelerate FTC onboarding and examples.

Description

• Added compatibility aliases to AutoDsl.AutoBuilder (add, doInstant, waitFor, ifElse) and updated valleyLib-core tests to cover them in AutoDslTest.
• Added PlayStation-style trigger aliases to CommandXboxLike (cross, circle, square, triangle, l1, r1) and a forDualShockLike(Gamepad) preset to CommandGamepad.
• Introduced sample starter classes under valleyLib-ftc/src/main/java/com/vcs/valleylib/ftc/samples: SampleDriveHardware, SampleIntakeHardware, and SampleAutos with example PedroAutoDsl routines.
• Updated README.md with a new "Compatibility and sample starters" section pointing to the new helpers and sample locations.

Testing

• Ran the core unit tests for the auto DSL with AutoDslTest, and all assertions passed.
• Built the project modules locally to verify compilation of the new FT C samples and core changes, and the build completed successfully.
