Restage with descriptive titles: agent arc first, network arc second

- New execution order: Now → Neurosymbolic Agent → Lisp Machine → AI Inference → Social Protocol → AI Weights → AI Training → What Remains
- Rename files to match (stage-1-gate, stage-2-lisp-machine, stage-3-inference, stage-4-social-protocol)
- Remove stage numbers from titles: just descriptive names
- Sequential weights 10-17
- Update nav links and stage table in _index.org and architecture _index.org
- Rebuild: 145 files, 0 errors

 The full architecture — gate-verified Lisp machine on custom silicon — is the destination. The staged roadmap (see the [[file:/stages.org][stages]] directory for full detail) describes how each successive replacement eliminates a class of threat:
 
-Stage 0 (current: Linux + Python agent + SQLite), Stage 1 (social protocol + provable communication), Stage 2 (the gate as software — root eliminated), Stage 3 (bare-metal Lisp image — no MMU), Stage 4 (in-process LLM inference), Stage 5 (neural weights as plist data), Stage 6 (verified fine-tuning), Stage 7 (what remains — physical, political, oracular limits).
+Stage 0 (Now: Linux + Python agent + SQLite), Stage 1 (Neurosymbolic Agent: the gate — root eliminated, provenance store operational), Stage 2 (Lisp Machine: bare-metal — no MMU), Stage 3 (AI Inference: in-process LLM), Stage 4 (Social Protocol: provable communication), Stage 5 (AI Weights: plist-native neural data), Stage 6 (AI Training: verified fine-tuning), Stage 7 (What Remains — physical, political, oracular limits).
 
 Each stage is independently useful. Stage 0 is running today. The migration is progressive component swap, not a cut-over.
