Follow-on to scheduler-sim-repl-verbosity: collapses the REPL's
per-event "[sim] t=... session=..." preamble to print once per
distinct rendered (timestamp, session) run of consecutive echoed
events, instead of once per event, in both step mode and continue
mode's structural-event echo. Requirement 1.3 deliberately keys the
dedup on the rendered, second-granularity timestamp rather than the
raw nanosecond clock value, which ticks on every event and would
otherwise never repeat -- confirmed against a real user-supplied
transcript before writing requirements (see research.md). Requirement
2 preserves event selection, ordering, content, every other REPL
command, and all scheduling decisions/state exactly as
scheduler-sim-repl-verbosity's Requirement 5 already established.
Generated via kiro-spec-quick (single-pass, no approval gates) with
an inline requirements review gate, an inline design review gate, and
an independent task-graph sanity review (one NEEDS_FIXES round,
repaired: added file-size watch bullets to tasks 1.1/1.2 per
design.md's own housekeeping directives).
