review fixups: wake-budget test coverage, drop cli.md churn, docstring

Addresses adoption-review findings for PR #818:

- Add table test TestDaemonConfig_MaxWakesPerTickOrDefault covering
  nil / zero / negative / positive branches plus TestParseMaxWakesPerTick
  for the TOML round-trip. Pins the <=0 fallback guarantee the PR
  description relies on.
- Drop ~516 lines of docs/reference/cli.md reformatting churn from this
  PR. That was genschema table-formatting churn unrelated to the
  wake-budget change; it belongs in a separate chore(docs) PR.
- Extend MaxWakesPerTick docstring to name the thundering-herd tradeoff
  (restart burst vs steady-state throughput) that the original constant
  was chosen to bound.
