chore: refactor protocol metainfo for debugger pause and snapshot phases

[pavelfeldman]

Summary

• Replace pausesBeforeAction/pausesBeforeInput with pause/isAutoWaiting/input fields in protocol metainfo
• Make snapshot capture phase-aware (before/after/input) for more precise tracing
• Move getMetainfo from protocolFormatter.ts to protocolMetainfo.ts
• Refactor debugger pause logic to use new metainfo fields, skip internal calls early
