🧹 Janitor: Refactor format selection logic to use a map

[google-labs-jules]

🧹 Code Quality Improvement

📊 What Changed

Refactored the output format selection logic in api/index.go. The switch statement that handled "html", "md", and "json" formats has been replaced with a map of handler functions.

🎯 Why This Helps

This change improves code quality in several ways:

• Modularity: Each format's logic is now encapsulated in its own function.
• Extensibility: Adding a new format is as simple as adding a new function and a map entry, without touching the core request handling logic.
• Readability: The main handler function is now simpler and its intent is clearer. It delegates the formatting task instead of containing all the implementation details.

🔍 Before/After

Before:

• A switch statement directly inside the main handler function managed all formatting logic.
• Adding a new format required adding a new case to the switch, increasing the function's complexity.

After:

• A map[string]formatHandler called formatters cleanly maps format strings to dedicated handler functions.
• The handler function now performs a simple map lookup to find the correct formatter.
• The code is more organized and follows the Open/Closed Principle more closely.

✅ Verification

• Tests pass (go test ./...)
• Linter passes
• No behavior changes
• Code review approved

📝 Notes

This is a pure refactoring and introduces no changes to functionality.
