## CAMEL-26355: Add MCP prompts from Camel routes
### Motivation
Add support for exposing Apache Camel routes as Model Context Protocol (MCP)
prompts, allowing MCP clients to invoke reusable, parameterized prompts
implemented using Camel routes.
### Description
This PR introduces a new `camel-ai-prompt` component and integrates MCP
prompt support into the existing Camel MCP server infrastructure.
Key changes:
- **New `camel-ai-prompt` component**
- Exposes Camel routes as MCP prompts using the `ai-prompt` consumer
endpoint.
- Supports prompt names, titles, descriptions, tags, and configurable
arguments.
- Makes prompt arguments available to the Camel route as message headers.
- Supports returning a single string or multiple messages with user and
assistant roles.
- **MCP server integration**
- Adds prompt registration, discovery, execution, and removal to the MCP
server bridge.
- Supports exposing prompts selectively using the configured MCP tags.
- Handles duplicate prompt names across tags and promotes another matching
route when the currently published route is stopped.
- Adds prompt execution timeout handling and sanitized error responses.
- **Transport support**
- Integrates MCP prompts with the existing streamable HTTP and stdio
server engines.
- **Camel Main configuration and metadata**
- Adds `mcpPromptTimeout` configuration.
- Updates MCP configuration descriptions to include prompt support.
- Updates generated component metadata and catalog documentation.
### Tests
Added and extended tests covering:
- Prompt execution and argument handling.
- Multiple prompt messages and assistant responses.
- Required argument validation.
- Tag-based prompt selection.
- Duplicate prompt name handling and route lifecycle.
- Invalid prompt results and sanitized execution errors.
- Prompt execution timeout and interruption.
### Build verification
Successfully built and tested the relevant modules:
- `camel-ai-prompt`
- `camel-mcp-server-api`
- `camel-mcp-server`
- `camel-main`
