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.
