Pull request overview

Adds an opt-in “dump simulator DB” workflow to the perf trigger so emulator runs can persist a simulator.db artifact per checkpoint result directory, and the reset logic cleans it up when needed.

Changes:

• Add dump_db: bool to EmuConfig and plumb it from CLI (--dump-db) into run configuration.
• Extend remote emu invocation to pass --dump-db --db-path <result>/simulator.db when enabled.
• Add GCPT.db_path and delete simulator.db during reset_running_gcpt() (when present).
