CAMEL-23397: Support route tool annotations (returnDirect) in camel-o…

[mcarlett]

…penai agentic loop

Adds parity between MCP tools and route-based ai-tool tools in the camel-openai agentic loop. camel-ai-tool gains a returnDirect annotation/configuration field (with a 5-arg compatibility constructor preserving 4.22.0 binary compatibility), camel-mcp-server publishes it via VertxMcpServerEngine, and camel-openai adds a new tags endpoint option to discover route tools from the shared AiToolRegistry, execute them through AiToolExecutor, and honour returnDirect to short-circuit the agentic loop. Route tools are refreshed dynamically as the registry changes, and manual tool-execution loops support tags-only route tools.

Closes #25497

(cherry picked from commit 2c3b65a)
