Closes #126

Summary by CodeRabbit

• New Features
  • Commands can now run in a fresh Node environment, directly on the host, or in the MediaWiki container.
• Improvements
  • Linting now runs ESLint in a fresh Node environment, while Phan and PHPCS run in the MediaWiki container. This keeps each tool’s execution environment consistent.

📝 Walkthrough

Commands can now be configured for fresh, host, or MediaWiki container execution. Lint tools select an environment: ESLint uses fresh execution, while Phan and PHPCS use the MediaWiki container.

Changes: Execution environment selection

Layer / File(s)	Summary
Environment contract and command configuration rs/src/types.rs, rs/src/exec.rs	ExecutionEnvironment defines fresh, host, and MediaWiki container modes. ExecutionHelper wraps commands with fresh-node and optional options for fresh execution, leaves host commands unchanged, or delegates container execution.
Lint environment routing rs/src/modules/lint.rs	ESLint selects fresh execution. Phan and PHPCS select the MediaWiki container. execute configures commands through in_environment.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

_{A rabbit packs a command with care,
Fresh-node hops through the open air.
Host stays still; containers roll,
Three paths now guide each linting goal.
I nibble clover, pleased to see
Commands go where they’re meant to be.}

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve the command configuration when wrapping it with fresh-node.

When a user supplies lint --folder for ESLint, rs/src/modules/lint.rs sets current_dir on the original command. This branch creates a new command but does not copy that directory. As a result, npm run lint runs from the caller’s directory instead of the selected folder. Copy the current directory and explicit environment changes to cmd before returning it.
