[diagnostics]

Summarizes CPU sample hotspots from collected runtime.nettrace artifacts for a GliderTrace session.

Why this tool exists

Raw runtime artifacts are usually too large and noisy for direct prompt use.

How it helps the agent

The model can ask for compact exception, counter, hotspot, or code-correlation summaries with stable session ids.

text	string	No	Optional case-insensitive filter across frame, method, module, and source path.
limit	number	No	Maximum number of hotspot summaries to return.
includeRuntimeFrames	boolean	No	Include runtime/framework frames instead of preferring user-code frames.
