### Description

- Add upfront session liveness check before attempting upgrade
- Try post/multi/manage/shell_to_meterpreter first (MSF native, ~30s max,
  no shell round-trips) before falling back to msfvenom+base64 injection
- Pass _whoami from handle_new_sessions to upgrade_to_meterpreter to
  eliminate redundant whoami shell command (~9s saved)
- Reduce shell_cmd timeout from 9s fixed to variable max_wait (5-9s)
- Add session liveness check between strategy 1 and fallback
- Refactor enrichment/reporting into _finalize_upgrade() helper

Previous flow took ~100s before first shell command, causing "Invalid
session identifier" on ephemeral bind_netcat sessions.
