v0.4.0

v0.4.0

✨ Added

• Added Linux event selectors with bounded capture capability (including enhancements to syscall/tracepoint/uprobes-related paths).
• Added NVTX range event definitions with bounded capture capability, supporting application-level interval timing analysis.
• Added GPU aggregate inventory capability (measure --aggregate), supporting coarse-grained inventory before precise measurement.
• Enhanced native framework symbol resolution (including observability improvements for framework scenarios).
• Added support for concurrent worker capture orchestration in multi-process scenarios (Skill/Agent workflow).

⚡ Performance

• CUPTI path optimization: only activate selected sources/callbacks, reducing capture overhead.
• Introduced incremental CUPTI snapshot streaming, improving stability under high load.
• Added filtering and boundary control for long-running framework kernel aggregation paths.

🧪 Tests & Contracts

• Added/expanded integration tests for Linux, NVTX, PyTorch, and multi-process scenarios.
• Updated protocol and JSON Schema (including aggregate inventory result structure) with contract test coverage.

📝 Docs

• Added usage guides for Linux event profiling, aggregate-first profiling, and NVTX launch injection.
• Updated Agent Skill workflow docs, emphasizing measurement paths driven by workload type and evidence.
