0.1.0.0

• Initial release.
• OpenTelemetry.Instrumentation.GHCMetrics: registers GHC RTS statistics as process.runtime.ghc.* metrics (requires +RTS -T).
• OpenTelemetry.Instrumentation.ProcessMetrics: registers OS-level process metrics following OTel semantic conventions (process.cpu.time, process.memory.usage, process.disk.io, etc.). Linux-only metrics (page faults, context switches, file descriptor count, thread count) require /proc filesystem.
