docs(architecture): correct plugin-abilities facts after its deletion

12-DISPATCH is the contract every subagent reads first, and its "current
runtime facts (so you don't guess)" section still told agents to inspect a
package that no longer exists. 08-STRUCTURE still deferred it to post-Stage 6.
Both would have misinformed every future dispatch.
