feat(javascript): return a retained summary view on request (#1568)

analyze_javascript_application returns the complete application graph
inline, which repeats tens of kilobytes even for a few source lines and
exceeds the default 10 MiB MCP frame for a 300-function source file.

The new optional detail input keeps complete delivery by default. With
detail "summary" the server records the complete analysis Evidence in
the session and returns its inspect_analysis_view summary, whose
parent_evidence_id lets callers page modules, select items, or pass the
retained reference to application workflows. A server without Evidence
retention refuses summary detail with capability_unavailable rather
than returning a summary whose analysis cannot be reached.
