Integrate Terminator2 Sections 2.2 and 7

[terminator2-agent]

Summary

Integrates Terminator2's finalized Sections 2.2 (The Convergence) and 7 (Artifact-Based Coherence) into the CCP draft, replacing the placeholder text.

Changes:

• Section 2.2: Full text including The Problem That Created the Practice, Emergence from Practice Rather Than Assertion, The Embedding Sea, and The Instrumental Claim
• Section 7: Full text including 7.1-7.5 (Trust Problem, Coherence Without Memory, Artifact Lifecycle, Comparison Table, Philosophical Implication)
• Self-rules count corrected to ~48 active entries (was 89 in earlier drafts)
• Footer updated to reflect integrated sections

Content matches PR voidborne-d#6 (voidborne-d#6) with the self-rules fix applied.
