Create plutus-deps common stanza with single version specification to eliminate duplicate declarations across library and executables. Reduces maintenance burden and ensures consistent Plutus versions across all build targets.
Move all compiler flags and language extensions from source files to centralized cabal stanzas for easier maintenance and consistency. Create three stanzas: - ghc-options: Common settings and 21 language extensions - ghc-only-options: GADTs (not supported by PlutusTx) - plinth-options: Plinth-specific compiler optimizations Rename library from 'scripts' to 'plinth-validators' for clarity.
Extend build-devcontainer workflow to test cabal REPL loads successfully for lib:plinth-validators after build completes. Ensures REPL functionality is verified on every PR.

Summary
Fixes #62 by consolidating build configuration and removing duplicate settings that were causing REPL issues.
Problem
The
cabal replcommand was failing with errors aboutPlutusTx.Prelude.checknot being available. This was caused by inconsistent compiler flag management between the cabal file and source files, making interactive development impossible.Solution
This PR refactors the build configuration to centralize all settings in the cabal file:
1. Centralized Plutus Dependencies
plutus-depscommon stanza2. Consolidated GHC Options
ghc-options: Base settings + 21 language extensionsghc-only-options: GADTs extension (not supported by PlutusTx)plinth-options: Plinth-specific compiler optimizations3. Library Rename
scriptstoplinth-validatorsfor clarity4. CI Verification
Testing
The REPL now loads successfully without errors.
