Fix documentation generation for examples with missing titles and update README

[Copilot]

The documentation generation process was creating broken links in the examples README when example entries didn't have explicit titles defined. This resulted in malformed markdown links like [](postgres.md) instead of proper descriptive links. Additionally, updated the main README to better reflect recent improvements.

Problem

The createExamplesReadme function in hack/examples.go was directly using example.Title without checking if it was empty. When examples in docs/examples/examples.yaml didn't have a title field, this created broken links in the generated README.

Solution

1. Fixed the documentation generation logic: Modified createExamplesReadme to use the name field as a fallback when title is empty, ensuring all links have proper text.

2. Added missing titles: Added descriptive titles to all examples that were missing them:

   • Database examples: PostgreSQL, MySQL, MariaDB, Redis, MongoDB, Memcached, InfluxDB
   • Messaging examples: Apache Kafka, RabbitMQ, NATS, Apache Pulsar
   • Web server examples: Nginx, Apache HTTP Server
   • AWS examples: DynamoDB Local, Timestream (Moto)
   • Simulation: Sim

3. Updated .gitignore: Added patterns to exclude log files that shouldn't be committed.

4. Updated README: Enhanced the Web UI key feature description to highlight real-time metrics monitoring, reflecting recent improvements to the metrics system.

Before

 * [](postgres.md) The postgres container image provides...
 * [](kafka.md) 
 * [](sim.md)

After

 * [PostgreSQL](postgres.md) The postgres container image provides...
 * [Apache Kafka](kafka.md) Apache Kafka is a distributed streaming platform...
 * [Sim](sim.md) Sim is a straight-forward API simulation tool...

All documentation has been regenerated and verified to have proper formatting and working links. The main README now better reflects the current capabilities of the Web UI including metrics monitoring.

Updated the README to highlight that the Web UI includes real-time metrics monitoring, reflecting the recent improvements to the metrics system in commit bbf8b77. The Web UI key feature description now mentions "monitor task status with real-time metrics" to better reflect the current capabilities.
