Description

It extracts common code under test/ to remove duplicates and enhance test readability and usability.

Key Changes

• Consolidate duplicate V3 (master) and V4 (manager) test files into shared _shared.go + _test.go pairs with table-driven version configs
• Delete ~30 redundant per-variant files (~5000 lines removed)
• Add reusable version-aware deploy and verify helpers to the shared test utilities
• Add watch-based verification utilities for faster and more reliable phase checks
• Extract repeated multi-line verification patterns into shared helper functions
• Inline single-use helpers and replace inline closures with reusable typed methods
• Remove redundant guard clauses, double-verification calls, and dead code
• Simplify variable declarations and replace hardcoded strings with constants
• Fix naming conventions, add missing godoc, and standardize comments
• Adopt shared helpers across appframework tests to reduce inline boilerplate
