Add the Ergasterion: Hickey, Fowler, Parnas architecture workshop

Pre-implementation architecture inspection for one proposed design at a
time, distinct from the Court's rulebook-level governance (which already
carries its own "Academy" self-identity in court.agent.md) and from
al-review's post-hoc diff review. Wired into al-complexity's HIGH-tier
route as the actual human architecture sign-off.

- Hickey: what does this model, and what's complected?
- Fowler: does this pay for itself, or borrow against the next change?
- Parnas: is what's likely to change hidden behind a stable interface?
  (proactive counterpart to Titus Winters' Hyrum's Law check in al-review)
