docs(pm-skill): runbook level rationale covers p1–p3, sweep line routes by the finding threshold (#16603)

Two line-neutral riders on `references/dispatch-runbook.md`, recorded at
flight Z's ACCEPT and outside that flight's declared file surface.

1. The level rationale explained only p0 / blocking / bug / age; the
   selection order also ranks p1 > p2 > p3 > 无级, so the rationale gains
   the level half: a ruled level is an explicit ordering, 无级 is a triage
   gap rather than a ruled low priority.
2. 「范围外发现照旧单开」 read as "every out-of-scope finding gets a card",
   contradicting the finding admission threshold; it now routes by that
   threshold and names where the rest goes.

The added line is paid by folding a same-file restatement — the emergency
section's summary sentence, whose content survives on the line above it.
File stays at 241 lines, every line ≤ 120 bytes.
