hanzo-mcp 0.15.5: ESSENTIAL_TOOLS = HIP-0300 axis surface

Replaces the legacy per-operation tool list (read/write/edit/tree/dag/
zsh/shell/open) in PersonalityRegistry.ESSENTIAL_TOOLS with the six
HIP-0300 axes:

  fs    bytes + paths    (read, write, edit, list, stat, apply_patch, search_text)
  exec  execution        (run, background, ps, kill, logs)
  code  symbols          (parse, search, transform, summarize)
  git   diffs + history
  fetch network          (get, post, download)
  plan  orchestration

Action-routed dispatch on top, not split tools — one tool per axis.
Keeps memory/think/critic/agent/config/mode/tool unchanged.
