feat(scheduler): show event time/session in sim echo, total sessions on replay load

Browse source 
repl_print_event_summary() (interactive REPL event echo) now prefixes
each echoed event with "[sim] t=<ns> (<human>) session=<N>", using the
same xce_core_now()/repl_format_ts_human()/session_count sources "info
session" already reports. Uses session_count+1, not the raw count:
events stream in and are echoed individually before the ReplaySession/
begin_round message that increments session_count is even read (file
order is event, event, ..., ReplaySession), so an echoed event always
belongs to the session about to begin.

Add sim_prescan_session_count() (sim.c): scans the replay file from the
current position via shape-only classification (mirroring sim_loop.c's
own ReplayEvent/ReplaySession/SnapshotEntry dispatch), counts
ReplaySession messages, then rewinds via fseek back to the exact ftell()
position -- same rewind technique sim_locate_and_load_snapshot() already
uses. Wired into sched_sim_driver_start(): prints "[sim] replay file
contains N sessions" once at load, non-fatal on scan failure.

Add test_replay_load_reports_total_session_count; extend
test_step_echoes_events_before_session_decisions with t=/session=1
assertions.
