Fix read/write tool output formatting

- Remove code fences (```) from read output - show raw content
- Show first 10 lines instead of 5 for read
- Only show line count for write if > 10 lines
- Remove indentation from read output
- Cleaner, more minimal tool output display

+The Quick Brown Fox and the Lazy Dog
+=====================================
+
+Once upon a time, in a forest clearing, there lived a remarkably quick brown fox.
+This fox was known throughout the woodland for its incredible speed and agility.
+
+Every morning, the fox would race through the trees, leaping over logs and streams.
+The other animals watched in awe as it darted past them in a blur of russet fur.
+
+Near the edge of the clearing, there also lived a very lazy dog.
+This dog preferred napping in the warm sunshine to any sort of adventure.
+
+One day, the fox challenged the dog to a race across the meadow.
+The dog yawned and declined, saying "Why rush when you can rest?"
+
+The fox laughed and zipped away, exploring distant hills and valleys.
+The dog simply rolled over and continued its peaceful slumber.
+
+As the sun set, the fox returned, exhausted from its day of running.
+The dog opened one eye and wagged its tail contentedly.
+
+"I've seen the whole world today!" exclaimed the tired fox proudly.
+"And I've enjoyed every moment right here," replied the lazy dog.
+
+Sometimes speed and adventure bring joy to life's journey.
+Other times, stillness and contentment are the greatest treasures.
+
+Both the quick fox and the lazy dog lived happily in their own ways.
+
+The End.
