feat: change default value of useAgentRules to true

- Updated default value in package.json from false to true
- Updated implementation to load AGENTS.md when useAgentRules is undefined
- Updated test expectations to match new default behavior
- Updated fallback values in Task.ts and generateSystemPrompt.ts

This enables AGENTS.md loading by default as requested by @mrubens
