feat: measured impact and attacker-goal proof standard for findings

Confirmed findings today assert impact in prose ("the attacker can dump
the table") with no number behind it, and nothing in the seeds demands
that a PoC demonstrate the attacker's goal end to end rather than the
presence of a vulnerable pattern.

Three changes, all in the default prompt seeds plus a guard test:

- worker and pentest seeds gain a "Finding quality gates" block: the PoC
  must show the goal achieved (data returned, command executed, another
  user's resource touched); a mechanism blocked downstream is a hardening
  note, not a finding; every finding carries a measured impact as a
  number with its denominator plus what the defense blocked, a proof
  basis line (executed live / executed lab / static unexecuted), bounded
  non-destructive testing rules (own objects first, at most three
  non-owned objects, smallest sufficient request, reversible values,
  touched IDs recorded), and a priority rule against standalone
  low-impact oracles.
- the reporter seed gains a mandatory "## Measured impact" report section
  (quantified outcome, denominator, defense-blocked facts, proof basis)
  and a "measured, not asserted" discipline bullet.
- a seed test guards all markers against silent removal.

Methodology adapted from VulnHunter (Apache-2.0, measured-impact and
attacker-goal doctrine) and bug-bounty-hunting-prompts (MIT, bounded
testing standard and priority discipline).
