docs: correct stale tooling and model references

Three migrations left their documentation behind:

wakeup.sh was replaced by the Makefile during the project structure
consolidation, but AGENTS.md and the e2e README still tell you to run it.
The log path moved to build/logs/server.log at the same time.

The local model moved to gemma4:e2b, but the e2e prerequisites and the
benchmark recommendation still name mistral-nemo.

The benchmark figures in CLAUDE.md predate the current model. Measured
2026-08-07: ~95 tok/s, full flow ~10-13s for simple turns, cold model load
~36s rather than ~8s. A turn costs three sequential Ollama calls and ~710
generated tokens regardless of how trivial the question is.

 ### 🧪 Local Development Setup
 * **Always test locally first** before committing and deploying. The build-deploy loop is slow.
-* **Start the local server** with `./wakeup.sh` - logs are written to `logs/server.log` for easy tailing
-* **Auto-reload**: The wakeup script runs uvicorn in reload mode - code changes are picked up automatically without restart (except for requirements.txt changes)
+* **Start the local server** with `make run` - logs are written to `build/logs/server.log` for easy tailing
+* **Auto-reload**: `make run` runs uvicorn in reload mode - code changes are picked up automatically without restart (except for dependency changes)
 * **Test REST endpoints** against `http://localhost:8777` using curl or similar tools
 * **Only deploy** when a phase or feature is complete and tested locally
 * **Environment**: Copy `.env.example` to `.env` and configure for your local setup (Ollama, Redis, Qdrant hosts)
