The profiler panel previously showed only platform calls, tools and tool calls, with the "Configured Platforms" metric hardcoded to 1, while the collector already gathered agent, chat, message store and store calls without rendering them.

As proposed in the issue discussion, this PR surfaces everything that is already collected - scoped to src/ai-bundle only:

• panel sections for Agent Calls, Chat Calls, Message Store Calls and Store Calls (reusing a shared message_bag macro extracted from the platform calls section);
• real per-component metrics (configured instances + calls) instead of the hardcoded platform count, and a "Configured Components" table listing each component with the service ids it was registered under (via indexed tagged iterators);
• the toolbar now reflects all component slices and counts every collected call.

A follow-up PR will add TraceableIndexer to symfony/ai-store and wire it into the collector.

Valid next step, but untested from my end for chat & message store component - thanks @sanya-misharin!

Just noticed while testing that this list is quite long now even if no message stores/chats are configured:

let's skip components that are not configured please.

Thanks for testing, @chr-hertel! Fixed in f269f63.

Every slice is now gated on the component actually having a configured instance, in all the spots you pointed at, plus the "Configured Components" table that had the same zero rows:

• toolbar: a Configured X / X Calls pair is only rendered when that component has a configured instance;
• metrics: the component list is built once and filtered, so the metric groups and the dividers between them only cover configured components;
• panel sections: Platform Calls, Tools + Tool Calls, Agent Calls, Chat Calls, Message Store Calls and Store Calls are skipped entirely for unconfigured components. The inner "No ... calls were made." empty states stay, so a configured but unused component still tells you it did nothing during this request;
• if nothing at all is configured, the panel shows a single "No AI components are configured." note instead of an empty metrics bar.

The docs paragraph about the panel mentions this as well now.

All screenshots below come from one and the same profiler token, rendered once with the previous template and once with the new one. The demo app configures no chat and no message store, so it reproduces your setup.
