Pull request overview
This PR adds a new flow cadence profile command that enables profiling of transaction execution on Flow networks. The command generates pprof-compatible profile data for analyzing transaction performance and resource usage.
Changes:
- Implements transaction profiling functionality by replaying transactions using FVM with forked state
- Adds comprehensive test coverage for validation, result formatting, and integration testing with local emulator
- Increases gRPC timeout from 5 to 60 seconds to support profiling operations
