fix(arborist): prefer direct dependency bins

[sanjayamaharjancodes]

Summary

• prioritize root and workspace direct dependencies when root-level bins collide
• preserve the existing depth/path order as the deterministic fallback
• cover direct aliases, workspace-root dependencies, and all-transitive collisions

Why

Hoisted direct and transitive packages can have the same physical depth. The previous depth/path sort could therefore let a lexically earlier transitive package claim a bin requested from a direct dependency.

This changes only bin-link ordering; lifecycle script ordering is unchanged.

Fixes #9868

Testing

• targeted Arborist rebuild suite
• complete Arborist test suite
• Arborist lint and template checks
