Jinwoo Hong bdb18003e0 test: add accumulated-workspace terminal typing reproduction (#20934)
* test: reproduce accumulated-workspace typing latency through real PTYs

* test: make the bench harness self-checks falsifiable

Review found four assertions that could not fail and one fixture gap:

- `missingPtyArrivalCount`/`missingEchoCount` were hardcoded `0` and
  `validateExpectedSeqs` throws before them, so every assertion on them
  was vacuous and every report read `0`. The throw is the real guard and
  is already covered; drop the vestigial fields.
- An absent status controller returned an all-zero result, which satisfied
  its own accepted-equals-generated equality. Assert presence first.
- The byte-pacing control had only an upper bound, so a generator emitting
  no stream bytes passed. Add the lower bound.
- `lineageEvery: 1` built zero lineage: no ordinal satisfies
  `% 1 === 1`. Offset the interval and cover the densest setting.
- The documented control command never set ORCA_TYPING_BENCH, so it
  skipped instead of running.

/**
* Entry point for the multi-workspace typing-latency bench
* (tests/e2e/terminal-multi-workspace-typing-latency.spec.ts).
*
* Usage:
* pnpm bench:multi-workspace-typing [-- --panes 8 --rate-kbps 512 \
* --keys 48 --cadence-ms 250 --cpu-workers 4 --worktrees 870 \
* --repositories 27 --terminal-tabs 1410 --unified-tabs 2000 --label before-fix]
*
* Results land in tests/tools/benchmarks/results/multi-workspace-typing-*.json.
* Run once per build/config with distinct --label values, then diff the
* totalMs/inputHalfMs/echoHalfMs percentiles.
