CAMEL-21658: Create a fat-jar launcher for Camel JBang
This commit implements a fat-jar launcher for Camel JBang that provides a pre-built distribution with all dependencies included. The launcher eliminates the two-step process where JBang first parses the .java file and then calls camel-jbang.
Key changes:
- Created a new Maven module camel-jbang-launcher
- Implemented a simple launcher class that calls CamelJBangMain.run()
- Configured Maven Shade plugin to create a fat-jar with all dependencies
- Created shell and batch scripts for Unix/Linux and Windows
- Configured Maven Assembly plugin to create distribution archives
- Used properties for dependency versions instead of hardcoded values
- Placed scripts in the root folder of the distribution
- Added example files in the examples directory
- Fixed Maven dependency resolution by including all necessary dependencies

+# Camel JBang Fat-Jar Launcher
+
+This module provides a self-contained executable JAR that includes all dependencies required to run Camel JBang without the need for the JBang two-step process.
+
+## Building
+
+To build the fat-jar launcher:
+
+```bash
+mvn clean package
+```
+
+This will create:
+1. A fat-jar (`camel-jbang-launcher-<version>.jar`) in the `target` directory
+2. Distribution archives (`camel-jbang-launcher-<version>-bin.zip` and `camel-jbang-launcher-<version>-bin.tar.gz`) in the `target` directory
+
+## Usage
+
+### Using the JAR directly
+
+```bash
+java -jar camel-jbang-launcher-<version>.jar [command] [options]
+```
+
+For example:
+
+```bash
+java -jar camel-jbang-launcher-<version>.jar version
+java -jar camel-jbang-launcher-<version>.jar run hello.java
+```
+
+### Using the distribution
+
+1. Extract the distribution archive:
+ ```bash
+ unzip camel-jbang-launcher-<version>-bin.zip
+ # or
+ tar -xzf camel-jbang-launcher-<version>-bin.tar.gz
+ ```
+
+2. Use the provided scripts:
+ ```bash
+ # On Unix/Linux
+ ./bin/camel.sh [command] [options]
+
+ # On Windows
+ bin\camel.bat [command] [options]
+ ```
+
+## Benefits
+
+- No need for JBang installation
+- Single executable JAR with all dependencies included
+- Faster startup time (no dependency resolution step)
+- Each fat-jar is its own release, avoiding version complexity
+- Can still be used with JBang if preferred
